I'm sort of in the same boat as others. Never a huge fan, but I liked to root for him back in the day. Recently he has become a little annoying and has lost heart/desire.
I can't think of many fights that would make sense for him now. You either have guys who will take his head off, or you have guys who aren't the name you need for a Forrest fight.
Only thing I could come up with is Wandy vs. Forrest at 205. Or a Rashad rematch?
