$55 NLTRN - river min raise

[soop]

Against what villians is this a push versus a call/fold?

12 hands in. This guy had bad sharkscope stats which made me want to push, but the thing is he seemed to be playing ok. He limped a fair amount, but raised on the button once and folded to a reraise, which I find this happens rarely against bad players. Also folded to a couple cbets and definitely hadn't gotten out of line so far.

Is this enough of a read to not push here?
