NLTRN - This is a major leak right?

[xSCWx]

I ran into this guy in a $33 SNG on Stars. He was definitely the best player I have run into in $33s, probably better than anyone I've encountered in the $100s as well, but it seemed to me that once the blinds got to 100+ his play became sub-par at best. This is a hand from his perspective, I'm curious as to if anyone can make sense of it. He had a 15% ROI @ 33s.
