We have the "luxury" of Texas and Marquette history of Shaka to help guide us to understand how subpar he is. Even with that, it still does not really make sense that Shaka was hired in the first place.
He was hired 4 years after the Final 4 run, where they went 5-1 (with play-in). After that, his teams we a combined 2-4 in the tournament. The final 2 years, he lost in the first round to a lower seed.
I spent a couple of minutes looking at VCU's 2010-2011 run, and it was a glimpse into VCU's peak performance during the regular season. Looking at info from Sports Reference, VCU was #2 in 3pt attempts and makes, #58 in percentage. They averaged 9/23.8 in games they won and 6.5/21.4 in games they lost. They lived and died by the 3 - and opponent turnovers. That was abundantly clear in the tourney. By my quick count, they had 12 regular season games with 10+ 3s made. However, they had zero in the final 8 games, where they went 3-5.
In the conference tournament (2-1), VCU averaged 8-20.7 from 3. In the NCAA tourney, they averaged 10.2/23.8 from 3 and 13 opponent turnovers. They got really hot while others got cold. In 4 of the 5 wins, their 3pt %-age was higher than the total FG percentage.
For the subsequent 3 years at VCU, their 3-point shooting was significantly worse. Shaka leveraged that outlier into a higher national profile and ultimately a better job.
Even after that f4 run, 2011 KenPom has VCU as the #53 team. Not that it matters...
