I think you're right in that his stats and tendencies suggest someone who isn't doing this with draws. Maybe not often, maybe not ever. Definitely might do it with 99-JJ IF he limp/called preflop. With 9 PFR I would expect him to raise that subrange UTG. More a question of 66-88 that are more likely to have limp-called and which may go all-in putting you on a draw (your image?) 66 kind of stands out and illustrates your point - if you are ahead he might have very good equity against you.

I don't mind a fold.
