Ok, heres my stance. The Yankees should not trade anybody for a third baseman.
They shouldn't trade for Crede, Atkins or Miguel Cabrera.
Furthermore, they shouldn't sign Mike Lowell.
Crede is a medicore player, coming off major back surgery. Plus, he'd likely cost the Yankees Johnny Damon. This would be a bad deal for the Yankees.
Go ahead and take a second to look at Garret Atkins home/away spilts.
He has hit .349 in Colorado, and .254 everywhere else..
Cabrera is a great player, no doubt. But hes going to cost the Yankees WAY to much. You don't trade stud pitching.
Mike Lowell is a great player at Fenway, but he would not be suited for the Yankees. Take a look at this article and this spray chart by River Ave Blues He would also more than likely be looking for a 4 year deal. Thats just to long.
The Yankees #1 concern this offseason, after Posada and Rivera, should be the BULLPEN.
Focus on building a dominent bullpen.
