Matt Kemp's name came up in another thread, and I thought I'd bring my response over to here instead: diehardtwinsfan, on 16 Nov 2014 - 2:39 PM, said: I'd rather have Kemp in left who can play above average defense I'm not able to take this assessment of his defense as a given. When a star gets moved out of CF, it's often after enough degradation that it's open to question whether he even can be average in left or right anymore. Here's an article with video that goes into depth about his defensive chops, and it's not complimentary. http://www.fangraphs.com/blogs/matt-kemps-wish-is-a-pitching-staffs-nightmare/ Some of the video looks nearly Willinghamesque (though in fairness he moves better than the Hammer did at the end). I give guys credit for playing through injury/rehabilitation, if that's what's being shown here, but then I also give Willingham credit for guts (bad back etc) without calling him a good defensive player. The numbers aren't kind to Kemp's defense, but there's not consensus here that state-of-the-art numbers count for anything even yet. I'd prefer an unbiased professional scout's opinion more than the Fangraphs page I linked to above, but didn't find one with a little bit of searching. I did find Kemp's self-assessment as of last May, here: http://nesn.com/2014/06/matt-kemp-red-sox-trade-wouldnt-benefit-boston-despite-offensive-woes/ “I just need to play better defense,” Kemp said last month, according to ESPN.com. “I’ve been bobbling balls, not getting as good a jump as I need to. … My legs are getting stronger and stronger, but I did come off microfracture surgery. I wish I was as explosive as before. I’m not hurt or anything, but you have those good days and bad days...." I'm not saying Kemp's defense is below average going forward, but I'd like some reassurance if I'm being asked to believe it's above.
