JJ over pair fashing over push (100nl)

[scallop]

Villian runs at 19/13/2 over 300 or so hands I feel that he rarely plays out of the ordinary and isnt very bluffy. I don't expect him to get out of line too often, which is why this hand confused me so much. I called the flop check raise because I felt that i was WA/WB and I wnted to re-eval the turn. Now he pushes, and I am finding it very difficult to put him on a hand. I thought his line only made sense if he had 77/TT/5x trying to get maximum value from an over pair, but that read didn't sit very well with my general view of the player.

Thoughts? Different approach to the flop would be cool also.
