Old Faces are Missing

[bsilliman]

Am I the only one to notice that a lot of referees who are not nationally known are officiating the Sweet 16?
Is this a direct result of the NCAA requiring officials to sign that waiver at teh beginning of the year?
Anyone care to comment on Dick Papparo officiating a final 8 game? Dick's best days are behind him and the coaches were certainly barking at him throughout the game, a lot more toward him than toward Tim Higgins and the other referee who I do not know.
