"Goes back to pop warner. You know every pop warner coach will tell you not to arm tackle, and that's exactly why. You got to put your chest on people you got to have your eyes up. Sky your eyes and do the right thing all the time."
So McCoy goes out with his second season ending bicep injury in 2 seasons, and Morris says he makes a Pop Warner level tackling mistake to get the injury? And that's after there was a serious knock on McCoy going into the draft about his upper body strength. He had only benched 225# 23 times at the combine.
I don't know what to make of this, but when your coach calls you out for trying a bad tackle even for 'Pop Warner' there is a big problem.
