As I recall, Nick asked for an extension when approached by Gardenhire about working out at first base. I can guess that didn’t land well with the Tigers front office.
My suspicion has always been that the Tigers weren’t really committed to keeping Nick. Again, Gardenhire was a temporary manager and it wasn’t a secret at all. To what degree Gardy really gave a crap what Nick said, one way or another, who knows. Maybe the Tigers were committed to bringing the team salary into a certain window and extending Nick would have created problems there.
so to answer your question, I don’t believe Detroit was interested in keeping Nick. They were getting top draft picks and opted to move on in that direction.
What’s your take?
Rereading this I’ll add, I believe if the Tigers had made a realistic and good faith offer early on Nick would likely have signed. I think things between the two parties had soured to the point that both sides weren’t interested in the end.
