MP2's line is very odd here. Check-raising on that board with 5 players in the pot is very dangerous with hands like top pair or a set of 7s. Therefore, I would think he most likely has a draw.

When I first thought about this hand I thought call and reevaluate the turn. Pushing is starting to seem better to me here. If pushing is wrong, it can't be by very much.
