If he gets a title shot after this then it once again just proves how weak the division is in my opinion. I'd like to see him have a rematch with either DC or Jones because he's basically the only guy in the division that can give them a real fight, but I think it should depend on how he looks vs. Glover.
If he beats Glover impressively, then sure, give him a title shot, but if he looks like shit, I think he should maybe have to beat someone else too then. It likely won't go this way and Gus would end up with a title shot no matter what, because honestly, who else is there in the division?
Either way I have Gus winning via KO/TKO since Glover is kinda slow, pretty hittable and doesn't have that great of a chin IMO. We'll see what happens though. Gus/Jones and Gus/DC rematches are much better than Glover vs. Jones or DC because Glover will definitely lose them, unlike Gus who actually has a real chance.
Gus beating Glover is the best possible outcome for the division as a whole in my opinion. More interesting match ups will happen if Gus wins. Glover will surely lose to both DC and Jones, so.
