I don't think he can do it.
The thing about Jones is he is in the perfect time to be champ, there are very few guys at LHW that aren't past their prime. Look at Jones' past competition and how many of them were legitimate contenders with room to improve still.
Really, the only guys Bones has fought that stood a chance were Evans and Machida. That's not to discredit Jones, he's excellent, but also lucky to be champ right now. Glover's problem is going to be his age and training partners. If he were 10 years younger and training with Anderson every day yeah he'd have a good chance but at 33 you are usually past your physical prime. Gustaffson won't do it because he lacks the proper training partners, I really have no idea who can beat Jones besides Anderson Silva. Such a disparity between the champ and the rest make it really boring to watch the division, someone tell Gustaffson to go live in Brazil.
