I'm open to the idea of trading Span, but it had better be for some quality talent in return. Otherwise, we should just hold onto him.
Also, there should not be any rush to make a move, and I would have to think that the Nationals would not be our only or even our best trading partner on this.
I'm don't buy into this idea that we have to deal him now because he's our most tradeable asset, we need to shake things up, and he's replaceable. I am not so dismissive of what Span brings to the table. He's a legit leadoff hitter and solid defensive centerfielder with a team-friendly contract.
He can be moved, but it has to be a move to help the Twins either now or down the road, not just for the sake of making a move.
