25NL AA SB, overplayed again?

[PinkSteel]

Villain was 44/19/2.0 over 86 hands. Seemed fishy. On one hand saw him min-raise A9o from SB after BTN limped, so I thought definitely not a *good* LAG.

But on this hand I wasn't sure if he had something up his sleeve or was just calling down. Could I, should I have slowed this down, and where? All comments appreciated.
