Spurs need depth in the frontcourt. Aldridge is on his last legs, and Rudy's on the last year of his deal. Add Vuc and re-sign DeRozan, and that's two all-star level players on the squad. Spurs got too many guards right now, so I'd take an uber-athletic forward for an uber-athletic guard. Hence the Gordon part. And I could see Gordon vibing with the younger players on the squad.
Lineup would be:
Murray (signed long-term)
White (signed long-term)
Johnson (rookie deal)
DeRozan (re-signed long term)
Vucevic (two years left on deal)
Bench:
Mills (expiring)
Tre Jones (rookie deal)
Vassell (rookie deal
Gordon (would be an expiring next year).
Poetl (signed long-term)
Samanic
