Geno is good at making adjustments. His problem was that some of his players were not playing up to their potential. After the BET loss to ND, the UCONN players decided amongst themselves what they each had to do to defeat ND if they met in the Final Four. With that attitude adjustment among his players, all Geno had to do was rewatch video of the last 2 games and give his players a different strategy to execute and his players executed it.
Geno also did a better job coaching the game Sunday night. When momentum was shifting towards ND and his players looked a bit lost, he would call a timeout. That halted ND's momentum and rhythm and got the UCONN players back on script with their plan.
