They also haven't suffered the injuries and transfers that we have over the last year. We have had 3 transfers (Justin Cobbs, Paul Carter, Devoe Joseph), and 2 injuries (Mo Walker, Al Nolen). Of those 5 (3 of whom were point guards), 3 or 4 probably would have been major contributors on this team, as Justin Cobbs probably wouldn't get much playing time if we still had Al and Devoe here and healthy, and Mo was a promising freshman, but still just a freshman.
How would Ohio State look if they were missing their senior leader (Lighty), their primary true point guard (Craft), their freshman big man (Sullinger), and a forward (Lauderdale)? That would leave them with DeShaun Thomas, William Buford, and John Diebler out of their 7 man rotation. I realize you can't really equate the contributions of Walker with with those of Sullinger, but then I also only removed 4 OSU guys to the 5 that Minnesota has lost.
You can still see that they would be severely underhanded and would end up having to play guys who weren't supposed to play. They would not be #1 (or #2 or 3 after losing to Wisky), they wouldn't be running away with the conference title and would maybe be attempting to compete with Purdue and Wisconsin for it. They would probably be only as good as we are right now.
But they have been lucky enough to not suffer a single injury to their somewhat short rotation all season, and, like probably 95% of teams, has not had anyone transfer, much less 3 GUYS IN ONE YEAR.
This has been a disappointing year, but you can't blame it all on Tubby. A lot of teams would be in rough shape after what we've been through this year.
