JDS is going to beat Carwin up for 3 rounds. JDS by decision.
Much better standup, 10x better on the ground, much better cardio+ Carwin looks like he's 70lbs lighter so he can't expect to just throw JDS against the cage and pound him.
Carwin could always score a KO with his heavy hands but I highly doubt it.
Carwin's wins have all come against guys who had shit stand up or were 10x weaker than him physically, or both.
