I play in a kinda serious flag football league (don't laugh, I live in Fl, a few D1 college players play in our league. Along with a couple of NFL washout's) I pulled my groin getting juked by a high school kid. I played the rest of the season, but I couldn't ever reach full speed, and couldn't cut on my left leg. As long as I played, it didn't get better.
For why it's worth, after the season ended it heald up fast. So fast I kind of forgot about it.
Woods is going to have a breakout year IMO. I'm sure he feels he has a lot to prove. He plays with passion and now he has a chip on his shoulder.
