If he's on tight and/or passive tilt and isn't the type to 'go apeshit on the turn with bad hand values', then I would imagine that he would raise 88-TT on the flop. I think you are looking at 77, 22 or a 4 most of the time here.

Honestly, given my read, he should never have 22 or a hand that contains a 4. Let's handread a bit here. I think this particular player is more likely to raise 77 on the flop when fishy passive players are more likely to call and tie themselves to the pot. When someone with TAGy tendencies calls a flop with passive players left to act then raises the turn, I'm less likely to give them credit for a big hand than some kind of free showdown play with a weaker made hand.
