WHAT DO YOU THINK??

[obi---one]

SO-
I am in the big blind in a 15-30 hold-em game. UTG open raises and I watch as the entire table calls, a family pot. I am in the big blind. I call with out looking. Do you think this is a good call? Is it a good call if I have 2-9 offsuit? Is it a good call if I have A-2 offsuit?
Does it matter that I play better than everybody at the table? If I played worse than everyone at the table should I fold? How is my play changed because the entire table is in for two bets....
