His flop raise could easily mean several differet things:

- a bluff/re-steal into a raggy board
- a set of dueces
- a wrap or draw+pair
- overpair+ draw
- he's a donk

While holding the 7 and 3 make it less likely that someone has 7-7-x-x or 3-3-x-x, I wouldn't discount the possibility completely on the flop.

Calling the reraise here is really dependent upon your read of the opponent. If I know the guy is a complete rock or otherwise unlikely to be raising a draw/steal, I am folding to the reraise without a second thought.
