Not really.
Kyrie and DLo both were good at catch and shoot. Kyrie has played in offenses where he shares the ball handling and distribution (no DLo isn’t LeBron but Kyrie has played heavy minutes with ball dominant players).
DLo also isn’t a small statured PG. He’s 6’5” he can play the 2.
Would allow the Nets to run a lot more on ball P&Rs and off ball screens that can lead back into P&R. Depending on the lineup there can be a few shooters and ball handlers on the court at once.
And also Kyrie is a 33 minute a game guy. That means DLo can get 15 minutes where he runs the offense. Kyrie can get a similar stretch. And they have their time together.
If DLo doesn’t fit. Spencer Dinwiddie really doesn’t fit. Might as well not have any backup because you’ll be wasting him and he won’t fit
