It depends. If MSU could defend 4th and 13, they'd have beaten ASU and Illinois, and be playing for 8-4. But what's their best win? Indiana? And in those 4 losses, even though all were to top 15 teams (OSU, UW, PSU, UM) they weren't competative in any of them.
So generally I'd say 8/9 wins going into the bowl is good, but it depends on (a) the schedule and (b) how they looked in the games against the best teams
