Villan is a little loose preflop, but other than pretty standard. Does he have "just" trips here often enough to make this call?

He played it like an idiot - he didn't raise on a draw heavy board when he had two oppurtunities to, and if he did he would have gotten way more or even possibly stacked you on the river.

I can definitely see the justificaiton behind calling though - I just don't get raised a-lot on the river as a bluff when I triple barrel.
