Actually I don't think any of them are deserving of a title shot right now. But if one of them was to get it bisping should be the gatekeeper. Babalu should fight all three of them. The only one with a chance against Renato is Bisping. I would think Babalu would win though.
Right now Rashad, Forrest and Bisping are all relative newcomers. UFC needs to get more veterans with a higher skill level. Before I will commit to any of those guys getting a DESERVED title shot.
