I was not a fan of Alford, but it's not Steve's fault that Iowa chose to hire a coach with such a dramatically different playing style.
It's fairly obvious that many of the players leftover from the Alford regime weren't interested in (or capable of) playing in Todd's system. There's no blame to go around there, it was just an unforeseen situation.
Does it mean that Todd is a failure and can't win at Iowa? No, it doesn't. It means that it'll take longer to get there than most people were expecting.
It is entirely possible that Todd won't win at Iowa, but I don't think we know enough yet to make that determination. I see a group of talented, extremely young guys that can be built around, and I expect to see improvement in each of the next two seasons.
Based on what I see on the court today, my expectations would be that Iowa gets to around .500 or slightly better next year, and then to 20 wins (or so) in year 5. If Iowa fails to do either of those, then it's maybe time to start looking in another direction.
What I don't want to see is situation where the coach largely fails to live up to expectations, but continues to receive contract extensions anyway - and then ends up staying longer than he should because the school/AD doesn't want to pay the buyout.
