Getting the take down against Colby isn't the problem (well, it is but...). The real issue is securing anything remotely resembling a dominant position before he scrambles back to his feet. The guy does not stop moving and never rests on his back when taken down (which is rare); he's on a hip, hitting underhooks and back up. I fully expect Usman to take Colby down several times, but I don't see him doing anything with it and if Covington spends more than 1 minute total underneath Kamaru I'll be shocked. This fight will be decided in a boring wall n' stall fashion with a decent amount of time spent at range with some uneventful point sparring. Usman should win by a narrow margin, Colby will clamor for a rematch, no one will want to see said rematch after how boring this fight will be, and Marty will ride off into the sunset to get his 'rassle on against a bunch of strikers that are on deck to challenge him.
