Not sure I'd be having Gus below Teixeira. Glover still has a lot to prove IMO, would be interesting to see him against any of Gus, DC or Rumble who are all a step up from anybody he's beaten. Got to remember that outside of that Davis loss way back in 2010, Gus has only lost to three of the absolute best in the division. And when you look at it closer, the fight with DC was a split decision and some argue he won it, while many including myself feel he beat Jones on the scorecards too. Rumble is the only guy to go in there over the last few years and finish him. Looking at the fights with DC and Jones show us that Gus is right there even if he has now lost three of his last four.
I think Gus is right up there with Jones, Cormier and Rumble. I'd personally like to see him get Teixeira next.
