Hand from a cardrunners video

[JoeKing]

I was watching Mkind's most recent cardrunners video, and there was one hand i had a question about.

It was a $33 MTT and it was the final 3 tables i believe. Mkind had 44k with the blinds at 1k/2k.

Cutoff opens for 4k with a 59k stack and Mkind is in the BB with 88.
Mkind just pushed all in but i thought that was a bit of an overbet. Am i wrong in thinking this? Could he have gotten away with a raise to 12k-14k? Or maybe even a call?

It just seemed like pushing 20+ BB's to a min raise was a slight overbet, but perhaps i am wrong.

Any thoughts on this?
