Sign of today's times...we have to have someone or something to blame for anything that goes wrong...sometimes things just happen and it isn't anyone's fault...I promise you that kids do far dumber and worse things on their own time that can cause injury...Heck, you can get hurt walking across the street...whose fault is that? As for lifting, how exactly do you plan to get stronger if you DONT lift all year long?  I have never seen anyone gain significant strength taking months at a time off from the weight room

Do you remember when Trump said that Italy and the US have been allies since ancient Rome?

You replied so it didn't fall on deaf ears

If its up to the kid and he is competitor... he's going all in. 

I can't tell you how many kids I see every evening in the gym lifting weights (going heavy) after getting out of baseball practice.  Most if not all play football as well.  I also know for a fact these kids are working out during athletic period, then going to practice or a game.  Who do you blame then....kids, parents?  Not the coaches.
