[2NL] ATo, TPTK. Weird river shove?

If TPTK is no good on the flop, then what are you hoping to draw on the river when you call the turn bet?

The point being it takes his river shove for me to believe tptk is no good... when he bets flop and turn at this size, I have no reason to think our hand is behind vs his range. He doesn't look like he wants stacks in, at least until river. His sizing is so bad throughout that he's left with a stupid overbet on the river, I can't be folding tptk to a half pot bet on the turn.
