I have heard that too. I don't believe it. Squating is GPP for every sport apart from powerlifting. I doubt it really makes to much difference what style you use as part of yours sports SnC. Although given the greater muscle mass used in a back squat you will get a bit more 'bang for your buck' out of it, than a frontie. However its easy enough to do both.
Cus smoking and tripping is all that you do. Ohhhh yeaahhh
