This is an interesting one. Johnson is too inconsistent to really predict his performance. Still, when he's at the top of his game, he's only decent at best, while when he's not, he's basically fighting like a can in my opinion. The dude got finished by Amir Sadollah, enough said.
Swick on the other hand is a very good fighter, but he has been inactive for a long time. He looks like he's in good physical condition, but who knows how he will perform after such a long layoff. At least Johnson is a good come back opponent for him to shake off some of that rust against.
I'm picking Swick by decision.
