ESPN had some place "simulate" the Sweet 16 games 100 times, using actual data throughout the season. Below are the averages of the simulation based on all of those fictious games played. Probably doesn't amount to much info, but I guess every little bit helps... 
(For what it's worth, the simulator had the UAB upset over LSU in the first round...)
Simulator says: Illinois 75, Wisconsin-Milwaukee 65
Simulator says: Oklahoma State 80, Arizona 74
Simulator says: Louisville 84, Washington 80
Simulator says: Texas Tech 72, West Virginia 68
Simulator says: North Carolina 90, Villanova 78
Simulator says: North Carolina State 75, Wisconsin 73
Simulator says: Duke 84, Michigan St. 82
Simulator says: Kentucky 80, Utah 77
