Look at last years Brooklyn Nets team. Their 3 most experienced guys were Jared Dudley, DeMarre Carroll and Ed Davis. They combined for 31 years of NBA experience. The season before that when they were the young scrappy team that finished with the 8th pick that we hope to be this season their 3 most experienced players were Carroll, Jeremy Lin, and Mozgov. They combined for 23 years experience in that 2017-2018 season.
If we were to do Love for Collins, Little and Turner and assuming we end up trading TT our 3 most experienced players would be Turner, Henson, and Delly. That's 22 years of NBA experience. Almost exactly what BKN had last year. So I don't buy the argument that we wouldn't be able to develop all of our young guys. In fact you could make an argument that they'd develop more without veterans playing meaningless minutes ahead of them.
We aren't going to win a lot of games next season. There should be plenty of minutes available for 4 rookies on this team next year. We know 3 of them can fill Channing, Love, and JR's roster spots. All it takes if for one more of our vets who are only here for their contracts at this point to get shipped out. Brandon Knight might not even get traded and can simply be stretched. We could even add another player to the Love deal to POR. We might actually have to since we'd be getting 3 players back anyway. We could easily add Zizic to that POR deal and we'd be at 15 guaranteed roster spots. Stretch Brandon Knight and we're back down to 14 and under the luxury tax. Trade JR to a team that will waive him and get back a future 1st and now we're way under the tax and have an additional asset and an additional roster spot. That gives us more flexibility in a future trade with Clarkson and TT which seems inevitable at this point.
Being way under the tax and having a future 1st round pick secured for JR while TT and Clarkson are still on the roster at the trade deadline will give us increased flexibility if we want to trade either of them to a contender at the deadline. There's already interest in them now. Same for Delly. Regardless what happens I wouldn't worry too much about have 4 rookies.
