I think the biggest thing about this season has been the inconsistency.
Using Torvik's "game score" as a metric, UB has played 5 absolute dud games with a score of 21.0 or worse (every loss except UConn, they had a pretty average 52.0). At the same time, they've played 4 games with a score of over 80.0 (Harvard, W&M, Depaul, and CMU), which is around where teams top-50ish like Akron have been consistently playing. For the rest of the year, UB has been fairly consistently just-above-average.
Personally, I'm not ready to anoint this team as being back in the MAC mix until I see them put together some repeat solid performances. They played a great game against CMU, played a little bit above their season average against Miami, and played 3 of their worst games of the season in the other 3 MAC games. I don't expect them to play consistently like they did against Central, but we know they're capable of it. I need to see them do it more often, or at the very least show some consistent growth as the season wears on. They'll need to play better than they did against Miami or Ohio to come away with wins against teams like Akron, Toledo, Kent State, Ball State.
