FTP: Marathon HU SNG

I played one FTP sat and lost after a long HU with top pair king to bottom two pair (8 5). Then I played about 50 or so hands with this guy. He was chasing long shots, making bad folds, bad all-ins, but I couldn't get him.

I hated having to call with this hand, but I thought there was a good chance I was good, and the blinds were starting to take a lot of skill away if I waited for another hand. He pushed on the river after overbetting the flop and check-calling the turn.

Anyone have thoughts on the call? Steeler was watching and just said "Wow." I don't know if that's "Wow, you're an idiot!" or what.
