I haven't watched Polanco so many times as to be an expert, but the random sample of times he's played for my viewing pleasure has me pegging him as decent range with a sub-par arm for SS. People say he should work on strengthening the arm - like, that hasn't already been tried? If on a 1-to-10 scale for major league SS defense, where 5 is average (meaning damn good among all humans) and 1 means most players because they just can't play the position, I'd put Escobar at about a 4 and Polanco a 3. Escobar's fine as a utility player but a mild liability as a SS starter; Polanco a bit more so. But on a similar scale for SS offense, where 5 is again average (and below par for any other position on the field), Escobar's about a 6 and Polanco looks like potential to be an 8. He won't be in ARod territory (who else is?), but he could eventually deliver .300+ BA year after year, with a little pop and hopefully an improving walk rate as he gets experience. He could win Silver Slugger for his position some years. He's not a maybe, like Florimon was. You kind of have to keep him unless some GM knocks you over with a starting pitcher offer. Polanco needs to play 2B but is blocked. For a last place team, it's not the end of the world to stash Polanco at SS rather than trade him for less than full value. That doesn't mean he's a SS, long term. Actually, I suspect Dozier at SS and Polanco at 2B would be marginally stronger defensively, but that's not going to happen, for reasons of clubhouse chemistry and so forth; you may wish otherwise, but teams just don't move veterans very often. Long term, Dozier will eventually depart. I think right now it's just not expedient to trade Dozier, for business reasons, due to this late HR outburst; I expect fans' valuation of our second baseman has increased far more than competing GM's valuation has. That's why this dilemma is even up for discussion, and IMO will continue into 2017 if not all the way through it.
