Thanks for the help on mine!
I agree with the majority here in that Ellsbury is the clear choice if you're afraid of dropping out of 2nd. Additionally, he's going to help in 3 of the categories you mentioned that needed to jump for a chance at first, so for this season it has to be ellsbury.
I think for next year though, Braun is the better choice. Kemp probably has higher potential but at this point he's starting to become an annual injury risk whereas Braun's production has been steady since his rookie year.
