How many players do I need in the pot to be calling from big blind?

At a six handed table is it worth it for me to call 1 bet as the big blind if middle position has raised and the small blind calls?

I usually fold my rags here but there were a series of hands today where I would have hit trips, etc and it got me wondering if I'm playing too tight.

I can see value in that for 1 more small bet I have the potential to win alot. But I'm also trying to be more disciplined in not bleeding away chips.
