reason the Dallas Cowboys defensive end has been suspended for 30 of the past 32 games.Now that he's on the verge of playing after a year away from the NFL Womens Connor Williams Jersey , the former Nebraska standout wants people to know there are deeper issues of mental health that Gregory isn't comfortable discussing in detail publicly."I was self-sabotaging," Gregory said Monday in his first group session with reporters at training camp in California. "Anybody that deals with what I have to deal with and what I've gone through and understands the process of what I've been through, I think can understand there's also a mental aspect to it along with emotional."Gregory was suspended three times in less than a year, the last a yearlong ban for multiple violations of the league's substance-abuse policy. He missed the 2017 season and waited an extra six months to apply for reinstatement to try to improve his chances.The detailed application included letters of recommendation from several teammates, most notably 2016 All-Pro linebacker Sean Lee, and won the approval of Commissioner Roger Goodell in time for Gregory to join the Cowboys at camp.Gregory's time away included stints in rehab and therapy, and the 25-year-old acknowledged that he had to learn to take those efforts more seriously."It's not just somebody walking around carelessly doing what they want," Gregory said. "There's obviously a mental aspect to it that plays a big part in it for me that I've had to try to figure out. The moment I took a more serious approach to that with my therapy and the more people around me understood what I was going through mentally, made it a lot easier for me to get right."The Cowboys drafted Gregory late in the second round in 2015. He was considered a first-round talent before testing positive for marijuana at the combine.Gregory made it through his first season without getting suspended, missing four games with an ankle injury but going without a sack in his 12 appearances. The first suspension was announced in the offseason, followed by a 10-game ban before the four-game suspension had expired.He played the final two games in 2016, finally getting his first sack in the finale when the Cowboys had already wrapped up the NFC East title. The third suspension hit before Dallas lost a divisional playoff game to Green Bay."We try to keep our eyes wide open about what any issues a player might have coming in and we're optimistic if we put them in the right environment they can respond the right way," coach Jason Garrett said. "It will not be 100 percent successful. But we've had a lot of players who have grown a lot in our organization."The Cowboys brought Gregory along slowly at camp, first allowing him to participate in pre-practice walkthrough sessions. Individual drills in practice were next, and finally some 11-on-11 work for the first time this week.Owner Jerry Jones, never afraid to gamble on draft picks and equally willing to stick with them http://www.dallascowboysteamonline.com/geoff-swaim-jersey , said he thinks Gregory can be ready for the opener at Carolina on Sept. 9."We certainly have had players that have had challenges with dependence," Jones said. "Now the problem is reality sets in and you have numbers and roster spots. You get the old adage of, 'Well, he wouldn't be doing that for a down-the-line guy or he wouldn't be that tolerant of a down-the-line guy.' That's actually very true."Three years after vowing to Jones that he would do his best to overcome the issues that led to him slipping in the draft, Gregory is cautiously optimistic that can deliver with his second chance."I think first and foremost they like me as not only a player but as a person," Gregory said. "I've always tried to do the right thing. I know I always haven't. But I've tried. I think they realized I was a person in need and sticking by me throughout that tough part and even now has been real important for me to get back. And I think it's worked."The Cowboys and Gregory will find out soon enough.Cowboys vs. Panthers: Five things to watch in the game The Dallas Cowboys will be playing football on Sunday in a real game that will count in the standings. Can you believe it? The time has finally arrived. The Cowboys will square off with their first NFC South team as they travel to Carolina to face the Panthers. The last time these teams met was in 2015 and the Panthers gave the Cowboys a 33-14 Thanksgiving beat-down. Carolina came into that game 10-0 and finished 15-1 en route to a Super Bowl appearance.The Cowboys are hoping for different results this time as they look to get off to a good start in 2018. It’s should be a great game as these teams are evenly matched, but what are some things that could be the difference maker? Here are five things to watch when these two teams square off.Panthers DT’s vs. Cowboys interior OLThe Cowboys were going to have their hands full with the Panthers stud defensive tackles Dontari Poe and Kawaan Short no matter what, but the absence of All Pro center Travis Frederick is going to make it that much more challenging. Backup center Joe Looney has been solid in relief, but when you consider that he’ll have rookie Connor Williams on his left, that can create a cause for concern for Cowboys fans as they fend off two former Pro Bowlers.The offensive line is such an important part of the Cowboys success. They need it working to get Ezekiel Elliott going and they need it to keep Dak Prescott upright. Winning the battle in the trenches is going to be key for Dallas on Sunday.Which will effectively influence...Cowboys first-down efficiencyThere is no secret that the Cowboys are going to employ a heavy does of the running game. Keeping quarterback Dak Prescott in manageable down-and-distance situations is going to be imperative and the Cowboys offense will need to win on early downs to make that possible. With the tough defensive front of Carolina, it’s going to be difficult for the Cowboys to move the pile. Dallas will need to work in some bootleg tosses, play-action, and quick passes in order to keep the Panthers from overloading against the run.If the Cowboys get stuffed early or have some negative plays that put them behind the chains, then their offense could be forced to play uphill. It’s going to be important for the Cowboys to be efficient on first down.Randy Gregory vs. Taylor MotonThe Panthers offensive line is beat up as several key starters are battling injuries. One of those key starters is left tackle Matt Kalil who was selected fourth overall in the 2012 NFL Draft (by Minnesota). On Tuesday, the Panthers put Kalil on injured reserve, making him unavailable to them for the first half of the season.That leaves second-year tackle Taylor Moton to protect Cam Newton’s blindside. While Panthers fans are pleased with the progress of last year’s second-round pick Authentic Ezekiel Elliott Jersey , Moton is very inexperienced and only played five snaps last year.Opposing Moton will be another second-round pick who doesn’t have a whole lot of playing experience himself - Randy Gregory. However, the Cowboys young edge rusher has hit the ground running once he was reinstated by the league and he’s ready to show the world what he can do. This will be an interesting battle to keep an eye on as how well these players perform will have a huge affect on how successful these teams can be this season.Double-down on double-deuceChristian McCaffrey can be explosive when he gets in space and the Cowboys defense will need watch this guy carefully. McCaffrey can beat you as a running back, but he’s even more dangerous catching passes as the majority of his 1,000+ scrimmage yards last season came as a receiver. With Panthers coach Ron Rivera indicating that McCaffrey will get a heavy amount of touches, this could open things up for the second-year running back to have a big season.The Cowboys will counter that with the great explosiveness of All-Pro linebacker Sean Lee. And with the improved movement from Jaylon Smith, the defense has a good core group of players who can go after the ball carrier. When it comes to McCaffrey, the Cowboys better allocate an extra defender to track his whereabouts. He’s a slippery littler sucker and if they don’t have an insurance policy in place when one guy misses, it could turn into a big play for Carolina.The rookie receiversThe Cowboys didn’t select fan-favorite D.J. Moore in the first round, but the Panthers did. Dallas opted to wait until the third round to draft their new wide receiver when they selected Michael Gallup with the 81st overall pick. How well will these young receivers fan in their NFL debut?Devin Funchess is the Panthers top receiving threat at the moment, but with with the talent of Moore, it’s only a matter of time before he starts becoming more involved in the offense. Cam Newton has a big arm and if Moore gets loose deep down field, it could result in a big play for the Panthers offense.The Cowboys have an assortment of receivers and could end up dressing all six of them on the roster. It’s unclear what Gallup’s role will be, but he developed some nice chemistry with Prescott in training camp. Can the rookie makes a splash in his first NFL game?What will you be watching on Sunday?
