Jonas Gray burst on the scene for the Patriots last season, rushing for 201 yards and four touchdowns in a Sunday night game. Just as quickly, he was gone. 

Gray overslept and was late for practice, and coach Bill Belichick didn't give him another chance to showcase his skills. Gray was inactive for the Super Bowl. 

Gray learned his lesson. "The tough part for me was to watch it, and not participate in a matter I thought I should," he told Dan Hanzus of NFL.com. "But it's motivation going into the offseason. I just know I need to work harder, so I'll never get myself in that position again." 

Still on the Patriots, Gray believes he'll get a clean slate next season, and he's spending the offseason preparing himself for the opportunity. 

I tell them, I'm going to have a Jerry Rice/Walter Payton mentality where whatever you do isn't enough," Gray said. "I'm going to have a work ethic where I know, in my heart of hearts, I'm going to outwork everybody. That's what I hope to achieve
