Well, Monson is fighting Rizzo coming up here.
If Monson wins, why not have Arlovski and Monson go at it in November? They don't have a fight for Arlovski and if Monson wins, there is no reason he shouldn't be in the UFC with 2 big wins over Rizzo and Fujita.
I think it'd make for a very interesting fight with Monson choking Arlovski out.
IMO, Monson should still be in the UFC
