I love Carrington as the sixth man -- brings instant offense, quick points, high energy. Gordon as the starter makes all the sense to me, both from a leadership and a defense standpoint. Also, Whitehead and Carrington, though they play well together at times, offer overlapping skillsets; both need the ball in their hands to thrive, usually through penetration.
Another reason Carrington's sixth-man role makes sense: I'd play him a lot with Veer, while pairing Whitehead and Desi. Those two just know each other so well, they make each other better. Not in any way trying to diminish Carrington, who's phenomenal, but I think bringing him off the bench, either as a 2 or to spell Whitehead as point, makes the most sense moving forward. He'll still get his points and his minutes.
