That's a bit misleading, as you've completely eliminated the 2006-07 Big Ten record off of that . Just because Monson wasn't here to absorb a 3-13 mark doesn't mean Tubby didn't inherit a team that went 3-13.
Gopher Big Ten record 5 yrs prior to Smith's arrival: 29-51 (.362) (1 NCAA)
Gopher Big Ten record 5 yrs after Smiths arrival: 38-49 (.437) (2 NCAA)
While I agree that .437 has not met expectations and has been somewhat disappointing, it is about ten games better than the five previous seasons, which included two abysmal 3-13's.
