Final 4 Update

April 2, 2011
By

VCU and Butler have continued their run.  Before the tournament, I had them highly because they elevated their games in the regular season when playing good opponents.  They have both continued that and increased that trend. One confounding issue now with adding the “Raising their Game” (“Ag25″ in the table below) bonus is that...
