Kudos for underscoring this important but politically incorrect (here, anyway) point. Michigan had grown a little stale and boring -- virtually everyone agrees on that. We needed more speed. More ingenuity. Better conditioning. Lloyd had grown tired; he wasn't recruiting as hard.
Michigan was a good, solid house in needed of some repairs and maintenance. It didn't need to be leveled. It was a successful, stable program. It was, despite one or two off recruiting years, a magnet for the top QBs, linemen, receivers. All it needed was a smart young coach who would reinvigorate and exploit M's decided advantage over most teams.
Instead, we hire a coach who runs a system that doesn't appeal to as many NFL-caliber players. Some, yes. But not nearly as many. Which made sense at WVU, which didn't attract blue-chips. By going to RR's model, we basically eliminated our greatest advantages. If you've got a system in place that routinely corrals NFL-quality talent, and that works for many top-10 teams, why explode that system? Why not just improve it? See: USC, Stanford, Alabama, Wisky.
But I don't blame RR for this. He does what he does. I blame Martin. He could have hired any number of fine coaches who wouldn't have needed to sink the ship in order to save it. If we'd hired a better fit for our talents -- Harbaugh just for example -- we wouldn't be having this debate, because we'd already have a quality team.
Martin's candidates: Schiano (pro-style)... Les Miles (hybrid)...Rich Rodriguez (spread). First of all: Schiano? Second: clearly the AD didn't feel that M needed to make wholesale changes; he just panicked when his first two candidates balked. And chaos bred needless instability, which continued for three disastrous years. And counting.
