For colby backers One thing i will say for colby is in promos and previews he did mention exactly what he did wrong in the first fight and say he worked on it.
dropping his hands and lack of head movement were times he took a lot of damage in the first fight. He ate some clean jabs doing this that were super unnecessary . He wont be roy jones junior overnight but at least he wont be ronda edmen either hopefully.
He doesn't have a reliable way to get Usman's respect though. No power in his punches and the wrestling will largely be off limits. I think Usman crushes him here -- he does everything Colby does but better and has improved his striking tenfold while staying active.
edit: Just realized you basically said this on the page before that post.
