5,2 off suit -- is this a reason to play?

[rybones]

don't remember the exacts, but it is 5 handed and hero is in the sb with 5,2. The big blind is t200 and there is a t25 anti. utg calls, co calls, button calls and bb has never raised in his life. Do you throw in the extra buck to see the flop?

what if you are the big stack by a long shot?

what if you are exactly 10xbb after you post the sb?

thoughts?
