I don't blame guys for sitting out; if your goal in playing college football was to improve your game to get you to the next level for a pay day, you should absolutely sit out. If you came to do that AND fight with your brothers until the season is over, than you should play. Linder baum getting hurt didn't hurt his stock or cost him a dime. I have no doubt he doesn't regret playing in his last game as a Hawkeye, I'd be curious if Goodson is content with his decision.
I would be shocked if Jack Campbell doesn't play his last game in an Iowa uniform and I'll go as far as say there's less than a 1% chance of that happening if he stays healthy.
