Next GM Watch

[F Gump]

Here's a question. Why did Lindsey leave Dallas for Detroit in the first place? Differences of opinion on team building?

Promotion. 
Perhaps a victim of Nico's purge of people who were competent.
Or both.

He was a consultant ("senior adviser") with the Mavs. In DET he got a big title with (presumably) a significant raise and more power.
