Flood was one the of the most lost coaches we've ever had. It would be a tight race between Shea and KF as to which of the two was the more ill-suited for the Rutgers job.
With Shea, (at least after his debacle here), he went on the coach in the NFL and had success grooming QB's, so at least he showed some degree of football acumen, even though it certainly didn't translate to the college game, (not while he was here, anyway).
Flood, on the other hand, will be fortunate if he ever holds a coaching position again, ( and it certainly won't be as a HC if he does, unless it's at the D2, D3, or high school level, but even that's questionable). -He might, however, catch a break down the road and have one of his friends who's the head guy at someplace like Delaware or Hofstra, etc., throw him a bone and give him a gig as a position coach. But he had his shot at the big time, and we all know what the end result of that was.
Ash may be hitting some bumps now, but with the lack of quality depth he was handed and the injuries to key guys we absolutely couldn't afford to lose this season as a result of that depth situation, anyone coming in as the top guy here would be up against it. Even with that, though, there've been 3 B1G games where we were right there for the "W", but couldn't seal the deal. -That situation will change with CA recruiting high-caliber players that fit his system.
And for those predicting Ash's demise in a few years, I respectfully disagree. That's simply my opinion, of course, but I feel that if given a fair shot, Ash & Co. will get this thing rolling the way we all want it to.
