Combo draw on the button (400nl)

[deaders]

6max 400nl 6 handed.

Effective stacks $400

UTG is unknown and hasnt been at the table long but hasnt done anything retarded yet. SB is a pretty weak player, not particularly bluffy just a bit loose and generally bad.

UTG raises to $14, 2 calls, I call, SB calls, BB calls. Amazing table.

SB bets $54 pretty much instantly, folds around to me...

So how good is my hand looking? what is this guy donking into that many people with, and is raising here really correct? I think his range has to be largely bigger flushes and sets, or am I giving him way too much credit?
