500 buyin doctor home game

[furfur]

8 players start. Top 2 get paid. I'm not in hand. Just want to see if villain is as much of a donk as I think he is. Villain has been most aggressive player at table. He raised and called reshove w/ 10,3 citing "pot's too big" when he was getting about 2.5:1 on the call from donk in big blind. Hero has been TAG and restole once from villain. Blinds 50 and 100. Folded to villain in SB who has 1400 behind and makes it 300 to go w/ K,2o. Big blind goes allin for 950. Villain tanks and again says he's "pot committed" and calls. What's the worse hand ur calling w/ from villain's position? He's getting about 2.5:1 on his money but I feel like he can't like his odds against hero's range.
