They have a "Mic'ed up" segment on ESPN just now featuring Champ Bailey (now of Denver, formerly of Washington). He was standing in the end zone on a field goal try, joking with the referees asking if he could knock the ball away when it reached the cross bar and the ref jokingly said no - it was unsportsmanlike. But now that I think about it, is it actually written in the rules that you have to block the ball as it goes up, rather than comes down? Because a blocked field goal is a blocked field goal - it shouldn't matter if it's going up or coming down as far as I see it.
