As has been mentioned, if the BB is solid he's not just going to move in with any two cards against three opponents. He probably has a pair, an 8, or maybe a 4. Pot s/b $7100 (I think you left out the SB's $), so you're getting 2 to 1 to call. It's about 2 to 1 against you hitting your straight, but you may also have the two 4s as outs, and if you don't, you may be ahead. You're not in good shape if you lose, but neither are you out. I'd call.
