I'm comfortable with the range/glove/accuracy, and the offense relative to position, but how much will a 70 arm strength hurt him at SS? How low do you think is too low for a SS?

that guy is a 2b or 3b. Most likely will be mediocre at SS.

I'd argue worse than mediocre at SS.  The arm strength and the range aren't ideal.

I think you're in for a shock if you play him this season. 

Last season's offensive output was somewhat of a fluke, imo, even in Boston.  He's more likely to go something like .260/.320/.350 this season.  He'd need to be an average SS defensively to justify the bat, and he's well below average, to the point where many guys just wouldn't play him there.  He helped you last season, as a utility player, but I would not expect him to hit enough in that role to help you going forward.

I wouldnt use him as anything more than a bench guy. Not a good enough bat to make up for the poor DEF @  2B/CF/SS.. 

Yay, boogs!!!

His arm strength will produce plenty of negative plays. 

How the heck did he hit 20 homers?  He's a great utility guy to have, can play almost any positon decently....except SS and C.

Thanks all, especially for the input specifically on range and arm strength. Obviously in a perfect world, he's not a regular, but is used like last year, to spell guys and cover for injuries. But there were literally 0 decent SS on the market this year; I've got a defensive guy who won't crack .600 OPS, and I've got a 22 year old who could use at least another year in AAA since he's still worse defensively (and needs to progress offensively too). 

I'm not too concerned about contending this year, but we have a minimum win rule, so I'd kind of like to be sort of competitive. I guess we'll see how it goes for a while, and maybe get the defensive guy more innings against weaker RHP, where he won't be such an easy out.

In a bizarre side note, he came within one game of tying the world's record hitting streak as a rookie last year, but was stopped short at 33 (I know, kind of weak the world record is 34, but we're only 16 seasons in).
