to prepare your guys to tackle during the season and going too light on tackling in hopes to prevent injuries. I'm not judging coaches for not going hard enough during camp or saying that I would have known better... I'm just observing, now that "hindsight is 20/20", that there was probably not enough tackling during camp. It sounds like they've been trying to make up for it this week in practice.
I hope my earlier comment didn't offend you too badly.
