Rampage shouldn't even bother. He's done after looking like that. You don't just "go back to the drawing board" at 34 years old looking like that. At least he gave Glover his props tho.
Glover looked very timid and his cardio wasn't very good either. I'd say maybe give him Hendo or Sonnen next depending on the outcome of their fights to see how he does against a dude with a solid wrestling pedigree, maybe even Davis (I think Davis gets Ko'd easy tho)
