If we could take any of them to be our coach now, I'd pick in this order: Huggins, Kruger, Martin, Altman. I don't have an absolute rebuttal for anyone who picks Martin over Kruger, but I happen to feel more comfortable with Kruger's demonstrated ability to win over a longer period of time.
Huggins is just a HOF coach. No shame that the other guys don't measure up. And if we're just talking about what Huggins did in his one year at KSU, I still put him on top of that list. He absolutely rebuilt the place from scratch, bringing in top recruits and winning with what we already had here. I have little doubt we would've done better in Beasley's year if Huggins was coach. And at least equally as well as Martin did thereafter. But, hey, I can't prove that, so...
