Perry needs to bring it. At least for this round.
As far as good story tension development matters, Perry will have to take another beating or so...coming back each time...and then in the climax...nearly beaten to death...he must arise from near death (the ole Rocky resurrection scene) to come back in a determined rage of punches to win.
Dramatic? YES! Realistic? We'll see!
That is a really risky strategy. I really don’t see the point.
