Well, I certainly don't think it will destroy the franchise.
It's just that to me, Nance is a journeyman and they've been loading up on this type of pitcher since the start of spring training and to no avail.
I'd rather hang onto minor league assets and see what else shakes loose between now and the trade deadline.
From what I've read on Nance, he's injury prone and slots more as depth piece than a true high leverage arm...but the Twins will be using him as a high leverage arm. Always reluctant to trade for an older player, even if it's an A ball prospect going out, that is going to have to project to be more than what he's been his entire career.
