It's much a clash of styles as who's the harder puncher.
Pavlik the pursuer will probably win a decision and outland AA.
Pavlik is not as open as Mirinda and Abraham is suspect workwise .
I think AA likes to work on the front foot but is adept on the backfoot his level of opponent has been pretty average whereas Pavlik with the exception of Rubio has been pretty much consistent.
Comparing Hopkins and Abraham defensivly is a bit misleading , Abraham likes to throw hard shots and then get out of range whereas Hopkins picks straight punches in particular the well timed right and then likes to smother , AA uses the ring more but is obviously stealing a rest as he does .
That could play into Pavliks hands he doesnt mind taking a few to get his own home and if he can cut the ring off and engage AA consistently over the 12 rounds I see him winning.
