$215s - Big Stack Play

[Unarmed]

Alright, I'm pretty passive with the big stack on the bubble. My theory has always been: unless there's a shorty to exploit, chips = time, and time = the luxury to not have to expose my chips to a coin flip.

Anyway, on to the hand:

Blinds are 200/400
Hero (4500)
Button (1800)
SB (1700)
BB (2000)

I am viewed as somewhat of a maniac.
All the other players seem pretty solid except SB.
He's one of those guys that is always begging people to call pushes so he can sneak into the money, but he's never willing to step up to the plate himself.
I'm dealt 79o and fold without a second thought.
Should I be a least considering shoving this?
