Meh. Each brings a different skill, I like Irving's ability to get to the rim and score plus hit some jump shots to go with Russell's length and nice pull up jump shooting. Plus I believe if you keep both it's likely one develops into a better player by his 3rd year in the season.
Also, I think the Sprads can't push the ball talking point is over done, and I don't think he's incapable. He pushes the ball fine, he just doesn't try to penetrate like Pullen, and I'd say half the time that's a good thing. It's not like Sprads will force us to play at 65 possessions a game or something.
