This isn't a fantasy team. They are led by two young players. Kemba can come back 100% but I still maintain depending on him and Smart to be this team's backcourt isn't a good idea. They just don't compliment Tatum and Brown at all. They are ball stoppers.
I don't agree at all. I think both Kemba and Smart make decisions fairly quickly with the ball. Smart looks to pass more than Kemba does, but I don't see either of them as a detriment to J&J.
Maybe eventually either Jayson or Jaylen will develop enough court vision and passing acumen that they can run the offense. In that case, it'll be better to have guys like Seth Curry and Danny Green around them rather than guards in the vein of Kemba and Smart. That's not the current situation.
I would prefer to have a player like Malcolm Brogdon, for example. A younger Kyle Lowry would be the perfect complement to Jay & Jay.
If you move off Kemba, though, who are you realistically getting to replace him? Eric Bledsoe? Ricky Rubio? These aren't upgrades.
There's a balance to strike between talent and fit but I don't think there are any guys out there who seem like plausible targets in a trade who would be enough of an upgrade fit-wise to be worth the downgrade in talent / scoring ability -- assuming Kemba does eventually get back to 75-80%+ of what he was.
