This is true, but - is this the first place to make your improvements?
I think that trying to improve this narrow call, which my be a thin +EV call, is going to frustrate more players than it will help them.
I imagine, looking at just the way the hand played out, that his range here is much much much wider on the river than you think.
A8s, QTc, JTc, K9c, 67, A2c (or any suited A, could even be like A9d that turned a flush draw). I think that there is a big range of hands that show up here and you beat. That being said, if this is a profitable call it is likely very very close. You are probably not making a big mistake by either folding or calling here - at least at 25nl.
EDIT- I would also not be surprised if this was a spazzy over pair as well. I have seen people limp in with TT-QQ and then call a raise OOP. So its a big range that potentially does this here.
