rockdawg, I buy into what your PT said 100%.
So much is asked of these young pups. At their age, many do not have a clue, the other side of that coin is those that are "training them(?)" don't have a clue.
Football has changed. I remember not lifting weights, lots of running, (hated laps) and we did stretching exercises. Had a great high school coach that played for Georgia.
Cannot remember single hamstring by anyone being pulled or stretched or torn, that however was in the 1950's. Coached football in the Far East and like most folks, coached like I played and was coached. No "hammies" there. Just got our asses kicked by the First Calvary coming to play us while they were stationed in Korea.
Realize that I sometimes, maybe too often bring up boring subjects, but there is more to football than understanding the playbook.
Believe that many of the knee surgeries are a result of too much lifting. Strength is needed, but sometimes I think that this is not a four quarter arm wrestling contest.
Very good post rockdawg, will have plenty of time to talk about who is the strongest. Say this . . . . Georgia players in the recent past have gone to the NFL tryout camps and were the best with lbs. lifted. Just saying . . . .
