I think Shane has only the mildest punchers chance. I think he's shot. He was shaking his hands because he couldn't let them go against Floyd. That's a classic sign of a guy who can no longer pull the trigger. He can see the openings, but he can no longer act on them.

Shane has a chance because he's powerful and Manny is really only a lightweight (by today's standards). But I think if Floyd discouraged Shane, Manny will build on that and Shane will not make it through the middle rounds.
