OKC already opened its championship window, this move climbs them through it. Add off-ball offense, defense, size, outside scoring, versatility and vet leadership to a great team that is limited in all of those areas for one reason or another. Power rankings will have them over Boston.
Bulls get draft capital amidst their rebuild. They may request more picks for a package of Pwill and Vuc, but I think this is within reason.
Nets are even earlier in their rebuild, so they get some young talent to start expirementing with a young core - a young, two-way SG with great size (6'7) and a proven defense young guy in Lou on a good contract.
