Definitely. If he's finally starting to embrace the leadoff spot, under no circumstances do you f*** with that. Francona has always said his best lineup is with Ellsbury at leadoff and I agree.
Martinez will take Kottaras' spot I imagine. Here's how I see the lineup:
Ellsbury - CF
Pedroia - 2B
Martinez - C
Youkilis - 1B
Ortiz - DH
Bay - LF
Drew - RF
Lowell - 3B
Lowrie - SS
Bench
Varitek - C
Green - UT
Baldelli - OF
Kotchman - 1B
obviously this team will probably have more different lineups than any other team in the majors from here on out but I'd say thats the ideal lineup
one things for sure though, the bench got quite stronger even if Lowell and Varitek (and maybe Ortiz) aren't going to be to happy about being there more often
