Yeah, that IS the question. Wiggy's in Coors Field now and if he holds onto the job (which, I don't see why he wouldn't), could be among the position leaders in HR's. He can also play 3B which is nice insurance at a thin position (or at CI where he's OK).
Zobrist definitely has the potential to be better in every category (although, I'd be surprised if he hit as many HR's). But, really, how much do we know about Zobrist? I picked him up as a FA the year he made his big splash and instantly loved him. But, dude was a flop last year. Is he a one-hit wonder? Lind and Wiggy provide a lot more certainty, I'd say.
So, while I generally go for the upside guys, I'm thinking that taking Lind in the deal and leaving Wiggy at 2B is the way to go right now. Though, I could change my mind in a few minutes...lol.
