shortstacked, push with 77?

[bobby rooney]

Stars 180 person SNG 20+2, down to about 1200 due to a severe lack of cards. Table is not overly tight or loose, but reasonably aggressive with most players coming in with a raise. Blinds are 50/100 guy with large stack raises to 400 in MP and another MP large stack just calls, I'm right after with 77. My image is squeaky tight assuming they've been paying attention. Is this an autopush?
