I think it's very weak.

It's more likely that he has a strong drawing hand than he has a made straight. He could have any junk like (2h 7h) or even and you're just going to fold? You're at least a 60%-40% favourite in the hand.

Man that's weak. Even in the off-chance that he's made a straight, you're still only a 65%-35% underdog.

This is a push.
