Hitting vs. Staying Healthy

My theory is this. I have coached in 3 programs. Came onto to a new staff in 98 on a program with 30 straight loses. Went 0-10, 1-9, and 6-5. We hit and hit and hit, we had to make football players, I left to a bigger school, this one went ont to go 10-2, 10-2, and 11-2. At the new school, more success, I begged to hit more because I knew what it had done. Went 5-5, 6-5, and 9-1 in 2003. In 03 we hit a ton. I am now a head coach trying to rebuild a program and we hit and hit.
Now for my theory.
You as the coach can not control injuries. Players are always going to get hurt, whether you are hitting or not, sprained ankles and so forth. You can't control it if you lose a game because of a player getting hurt. If you lose because you are not physically ready to play, that is your fault as coach.

Proper strength and conditioning is your best weapon against most injuries.

Teach tackling technique EVERYDAY. Every position on defense should know proper tackling technique this will reduce injuries because improper technique causes a lot of injuries. But, as for hitting, no question you HAVE to do it, it's the only way to properly prepare them for game conditions.
