It isn't "completely unfair" at all. During both his seasons at the helm, there have been Red flags about his coaching acumen -- lousy defense, broken offensive concept, predictable in-bounds plays, baffling substitution patterns, players regressing, etc. The notion that we need to assemble a super team to overcome questionable coaching is yet another Red flag [pun intended].
Even when his "best player" was on the court and healthy, we still struggled against low end teams like Le Moyne and Youngstown State. Blowout after blowout.
Just a counterpoint -- yes, we need more NIL resources. But the coach also has to demonstrate that they have the chops. So far, he hasn't. Our struggles can't just be chalked up to NIL -- that's a gross oversimplification.
