Defending your BB

[Hawt]

I have been playing the Stars MTT's a lot lately, and I am really having my big blind pushed around. I am trying to play tight and not get myself into any tough decisions with mediocre hands. It seems like my big blind is getting raised every round. I remember shabi saying something about how he is going to defend his BB everytime in another thread, I think it was a cash game though, not a tournament. I mean when you look down at something like J7suited and there is a 4x the BB raise and your the BB, should you call that or just give it up and wait for a better spot? I mean the best you can really hope for (realistically) is top pair with a weak kicker, and maybe two pair if your lucky.

Just wondering other peoples opinions on this.
