UNC typically gets fouled more...which is why they often shoot more FT's than the opposition.
I thought you Duke scholars were sharp?
There are two reasons for this:
1) UNC feeds the post a majority of their possessions where fouls are more likely from the defense.
2) UNC continually pushes transition, straight to the rim, and defenses are not set. This offensive attack also generates fouls at a high rate from players trying to recover.
Ref bias is not present..they are equally bad for all... so unless you want to start counting their failure to call the moving picks, along with the push offs, grabbing, tripping and other assorted "Tough D" Duke plays...I don't want to hear the whining
