Oh! Yes.. Stretching I only use to even out condition. I actively try to *not* use stretching. I think Cardio is safer, if it's a choice between them I go for the Cardio, even if the guys are a tiny bit more tired from it.

I think the game is biased to players who have the highest amount of activity, be it in games or training. These *are* often key players, but this is no surprise since they play the most. I can usually predict who is going to be injured, actually. (right before I hit that Stretch button I usually have that little voice in the back of my head tell me it's a bad idea)
