They WILL sign a right handed hitting second basemen to provide some competition for Wong in the spring, and to provide some depth now that Freese is gone.
Ideally, you find someone that can either help defensively enough that they can also play shortstop or third base (like Carroll), or you get someone who can sort of play the position, but be a massive bench bat (like Baker).
Ellis is probably one of the better right handed bats to play second that doesn't have to play every day left. Obviously Infante is going to get a nice deal.
Everyone here knows my preference, but Ellis wouldn't be so bad. Hell, he hit as well as Brandon Phillips last year. This isn't a core player, this is a bench guy you are adding, and Ellis isn't a bad player.
I think he'll require 1/3-5 million though, since he can't be expected to start.
