($22) AT tight table

Table was tight (button was a little loose early on) and SB is really tight and is a 2+2er, BB also tight by my numbers. Is playing AT terrible here? I don't think it can be played anyother way than push IF you play it at all. My image should be very tight as well...except that I had just pushed last hand and went uncontested. Blinds just got to this level.
