I have a feeling this is going to be a major unforeseen side effect of the NIL/Portal. Instead of these "underrated guys" at lower schools staying 4 years and then making magical runs in March they all transfer out before that happens.
The only way these teams have a chance is if they have a top-level coach. McNeese State - Drake - Colorado State etc. but at some point the talent will be too much for them as well but at least the coaching gives them a chance
Hopefully, the games get better as the tournament goes along as the teams become more evenly matched.
