last 4 in 20k tournament, facing push

[El Stuntman]

Hi all,

would appreciate opinions on the below MTT situation:

20k tournie guaranteed on iPoker last night

I am down to last 4

payouts as follows:

1st $6,345
2nd $4,230
3rd $2,115
4th $1,645

I have ~80k and am on the BB
SB has similar

other two have largeish stacks (250k and and 170k).

blinds are 5k/10k (10 mins left in the level) and it has degenerated into a total push-fest

two big stacks fold and SB shoves. I look down at 22.

Do I call??? I am getting varying opinions.
