Abusing UTG as a spot to steal may work for you but I think that's because you don't play 33's (correct me if I'm wrong). In the 33's you may even have someone shoving with a smaller pair infact I see this move quite a bit even at the 55's and in this case folding to the raise doesn't work out well at all.

In the 33's you will rarely see 7 people folding here to a 2.5 BB raise which is what you will need to steal the blinds.
