Man if Maggs was going to play like he did in 01, and 02, I would have to say him. Last season he had more at bats than 01, 02, but his HR's and RBI's were way down even with a .317AVG. I think his career years were 01, 02, and with Sheffield in that awesome Yankees lineup I expect a great and possibly career year from Sheff. So my vote goes to Sheff.
The best there is, was, or ever will be, it's me!
