not a chance. he's almost the most boring fighter ever. he basically spars with his opponents, stops takedowns, and only wins via decision. great strategy to win, incredibly boring to watch. he never finishes anyone, nor does he try. he never goes for knockouts. he's like Chuck Liddell minus the KO ability. BORING! He actually used to use his wrestling offensively, until he got caught and subbed in a guillotine. After that, he never went for takedowns.
Not a huge Jones fan but he's way more well-rounded, pretty dynamic on the feet, and has great offensive wrestling and control on the ground. He even has a few subs when decides to use them. Not even in the same league. Two different mindsets and strategies regarding fighting. Bones is a true mixed martial artist with an incredible arsenal of high level skills. Colby can box and stop takedowns. I know he can wrestle but we don't see it (other than sprawls) or a ground game.
I don't think PEDs would change that and not only that, i'm not convinced Colby's even natural anyway. Anyone and everyone is suspect and not above PEDs when it comes to the fight game IMO. I think Colby only says this stuff just to grab people's attention. He's like clickbait. Kind of like Conor, except actually gets into real life trouble. LOL.
