I'd never let a competitor adopt the mindset that every practice, game, situation wasn't important. There are 2 games left. Once you start letting them think some snaps are more important than others, they start deciding when it's important to play and when it's not. Losers mentality. If Rodgers gets hurt, he gets hurt. If he's too hurt to play then he is. If he's not, he should be out there. I think anytime you start approaching football as anything other than playing football, and start to adopt a, let's prevent injury mentality, you open yourself up for physical and mental downfall.
Rodgers skips all preseason and gets hurt in the 1st quarter of the 1st game. it happens. A bear defender gives himself up after a game sealing INT and I wonder what his damage was. Probably more than had he just kept running.
