I always think it's fascinating to see the highest RPIs left out of the tournament. So here they are:
33 Southern Miss
54 Florida St
58 Green Bay
61 St Mary's
Actually a pretty good mix of high-major and mid-major here. No trend can be discerned from this.
Worst RPIs to get an at-large bid:
55 North Carolina St
51 Kansas St
Again, no real outlier. This is a pretty quiet year. Normally when I do these, there's more volatility and clearer biases.
