Sorry, pb; this one always gets me as writers obsess over differences of 1/2" or so.
It matters...but only if the guy is a decent tackle as well. Otherwise there would be a lot of NBA players lining up at LT. It matters for the punch. It matters for locking a guy out from you so he can't get his hands on you. Cameron Wake has that awesome karate move to knock hands off of his chest. Without it the mammoth tackles lock you out there and control you. See Ogden, Jonathon.
