Sabathia came out recently and said he'll "play anywhere" but I agree, he wants to play on the West Coast. I'd rather see them throw big money at Manny and Texiera, and go after second tier guys like Burnett (just got done pitching an entire year healthy, so a good risk), Lowe (a nice #3 or #4 in the AL East) and possibly Sheets (higher risk than Burnett). You'll need more or less depending on whether Mussina and/or Pettitte retire.
Ideally:
Sabathia Wang Chamberlain Lowe Hughes
Less Ideally:
Wang Burnett/Sheets Chamberlain Lowe Hughes
Sort-of Ideally:
Wang Chamberlain Lowe Mussina Hughes
Not Very Ideally:
Wang Chamberlain Lowe Pettitte Hughes
Crap:
Wang Chamberlain Pettitte Mussina Hughes
I'd honestly let Dandy Andy go. He...is done. Mussina? Try to get him to come back, but Lowe is a must-have if he retires. Chamberlain and Hughes both will be in the rotation next year, no question. Wang leads. Burnett and Sheets are injury prone which means you need Lowe if you get either one of them to supplant in emergency.
