Another thing, Crawford switching southpaw on Spence is only going to give Spence an even straighter path to put his jab in Crawford's face. I don't think a lot of you are seeing what I'm seeing when I'm evaluating that matchup.
Crawford is a good counter puncher, but Porter keeps his hands low and loops his punches a lot more. Spence has a tight high guard and he is a straight line puncher. He does not lunge in and leave himself open like Porter. He does not leave himself off balance with his footwork like Porter. If Crawford tries to fight this way against Spence he will be broken down. Crawford would have to fight a lot more aggressively than he is used to as far as his punch output to open Spence up, which will leave him open a lot more as well, not to mention I still have no reason to doubt Spence chin. Crawford is an accumulation puncher bruh, he aint making guys do the stanky leg after one punch like that.
There is a reason I'm telling you I'll bet a rack on the fight if it happens, I'm that confident Spence wins.
