From the ever interesting Mike Boyle:

Not for Every Body
Not everyone is made to squat or clean. I rarely squatted with my basketball players as many found squatting uncomfortable for their backs and knees. It killed me to stop because the squat is a lift I fundamentally believed in, but athletes with long femurs will be poor squatters. It's physics. It took me a while to realize that a good lift isn't good for everybody.
