from my recollection, TD was rarely the guy guarding Stoudemire when Stoudemire took it to the hoop and missed, (or even made it)
TD usually got the easier defensive assignment, and even then failed, Frye made shot(s) over a lackadaisical closeout by TD in every game, and guards easily took TD to school every time he switched onto them, or when he came over as help D. sure TD got some blocks here and there, but that was when his defensive presence became a little too underestimated

when guards thought that he was of absolutely no consequence...
TD rarely turned away anyone in the paint, while our guards were consistently turned away by any and all of the Sun's Bigs
