Biggest problem with the flop call is your position. Let's assume like a previous poster mentioned you have 3 outs for the backdoor draws and 1 out for an ace... aproximately. This gives you sufficient odds to call but your position sucks.

1. It wouldn't be out of the question for UTG+1 to c/r this hand and you end up putting 2 sb's in with garbage

2. Even if your hand improves on the turn you lack position to make a good play on it (example: you improved and got suckered in for 2 bb's on an OESD).

Then the icing on the cake. You hit your hand after all these poor calls and check the river? Given the call on the turn you are treating your hand as an OESD, which means you are giving credit to the 9's as an out. You hit your 9 on the river and then check it through? If your afraid of a 9 then you shouldn't have called the turn.
