Resign Giambi

This is my pipe dream:

1) Yankees do not sign Teixeria.
2) Yankees sign Giambi to a $5M/1Y or $8M/2Y deal.
3) Giambi holds down 1B until Posada moves there or someone else takes over (because we all know Posada's going to need some time there before his deal is up).

My reasons are this:

1) Giambi is a great teammate; this may be not appreciated but is important.
2) .247/.373/.502, 128 OPS+, in 145 games.
3) Yeah, he's a terrible defender. But his WARP-1 (Wins Above Replacement Player, defense adjusted) was 4.5 for 2008. For comparison's sake, Jeter had a 4.4 WARP-1 in 2008.

Come on, Cashman, pull the trigger!
