No doubt tell him to not steal bases and I agree his defensive metrics are a concern in the last 2 years but he was an above average RF before that. And he's clearly not appropriate in CF for us and may even be primarily a LF in Fenway. I agree with all of that.
Which to a degree impedes his potential big money options. He's not projected to be as expensive as Ellsbury.
There are substantial positives though. He creams RH pitching. He got on base last year at a .420 plus basis which fits right in with the Redsox grind em out approach. He has the ability to play wall ball like few others in baseball. He's a "Pocket Papi" in the same way many countries had "pocket battleships" which packed a lot of punch with minimal displacement!
I'd like to know what happened to his range. Defensively he fell off the end of the earth in range, while he was a decent defensive OF before that. To a degree I think it may just be a bad year in 2012 and playing out of position in 2013.
The whole split issue is often just sample size. It is amazing how such things can just fluctuate over the course of a guys career. The bottom like is his overall numbers. If anything, in the Redsox situation of having a lot of depth, I actually like guys with a lot of split. They platoon better for the money. That may actually be one of the keys to boston's recent success.
Who knows what happens. I'm going out on a limb here. Sometimes I'm wrong but I think there is a real good chance Choo is our guy. Maybe a 25% chance even. If I had to pick one guy he would be it. He is a good fit in Fenway. They may end up trading Nava as a result but he's a good fit.
