Rate my team 6x6-8 team league

[TB28]

C-Soto
1B-Pujols
2B-Kinsler
3B-Atkins
SS-Rollins

Util-Adrian Gonzalez, Loney
Bench-Justin Upton, Billy Butler

Pitching
SP-Beckett, F.Hernandez, Zambrano, Sheets, Hughes, Lowe, Wang, Lilly

I know it's tough to judge in an 8 team league but I am fairly happy with my team.

Questions
Early on who's the better play Upton or Ellsbury, and between Loney and Butler

Anything I really need to address?

Thanks
