Why are there people who think Colby Covington will defeat Jorge Masvidal in the UFC fight they will have?

Why do people think this when Jorge Masvidal is bigger and more muscular and the same height and has longer reach? 

lol did you watch costa vs stylebender fight ?

colby will do what usman did to masvidal 

i didn't know they were even officially fighting, but i assume it's due to Colby having a huge wrestling edge as long as a huge edge in stamina.  People can dislike Colby, but the guy is really talented.  Gamebred obviously can put him to sleep, but this matchup more than likely ends up looking like the Usman fight for Jorge

Supposedly Colby had his way with Gamebred when they trained, in wrestling at least which is expected since Colby is known for that as his background. I see Colby winning this fight and he will grind away a decision just like how he mauled Tyrone Woodley. Colby is a better fighter than Ben Askren so don't put that into contrast.
