If the UFC wants to toss Mousasi a bone, give him Rashad Evans. If he defeats Rashad he solidifies himself in the division, and he's basically 1 win away from a title shot. If the UFC wanted to build Mousasi up they could give him washed up Rampage. I think worse comes to worse Mousasi gets paired up against Ryan Bader or Phil Davis.
Personally, I don't want him to go to MW just cuz I like kingpin AS, but it would be interesting if he did. He would fair a lot better against those chumps.
