Umile stumbled into his success. He literally inherited Kullen's 87 and 88 classes that produced 8 quality players (Winnes, Dean, Plavsic, McIntyre, Amodeo, Flanagan, Mitrovic, and Scott Morrow) and were the core as the program went from 7 wins to the 92 NCAAs. His own 89, 90 and 91 classes were pretty weak, complimentary parts to that 92 NCAA team. When Kullen's kids graduated, Umile's own recruits were inadequate, and the team slipped back to 18 wins in 93. Thankfully in 92 he got McCloskey, who then produced the next wave of kids who formed the core of the 94 to 02 run, starting with Bogi, Nolan and Murray in 93-94, and Mowers, Nikulas.
Essentially, Umile walked into a super situation, nearly killed it, then got lucky McCloskey came along. When he no longer could piggy-back off of the work of his assistants, his success ceased. You can understand the Borek supporters' lament that Borek -- for all of his own flaws -- really was asked to do too much on his own while burdened by Umile.
Now, managing this by delegating is not as easy as I make it sound, but Umile ultimately bears the burden of not having done enough to help during the good times to put them over the top, and not doing enough during the bad times to prevent the slide. That will be his legacy -- just enough to fall short.
