That seems like a rather superficial prediction based on no good evidence...it takes nothing into account about this particular matchup and you could copy/paste any opponent into the statement.
Maybe tell us why *Garry* not only can't handle Colby's pace, volume, and wrestling, but to such an extent that he will get stopped...despite the fact that this has not been the case for any of Colby's opponents for well over seven years, never mind that Colby will be 36 (tomorrow, actually) and likely isn't getting much better (certainly not the way a 26yr old Garry would likely be making improvements).
