Not familiar with Greg Stiemsma? We've gotta be honest. Us, either! But, apparently, dude is a former University of Wisconsin star who now holds down the center position for the Boston Celtics and delivers his fair share of blocks. Unfortunately for him, that didn't happen when John Wall took one strong to the hole on Monday night. And, as a result, the big fella got put on a poster. But, hey, he's gotta look at the bright side: At least everyone knows his name now, right?
