Smart is our glue guy, the hustler, the lock-down-D guy. He’s the number three guy no matter who becomes our one-two punch in our next Big 3. He is indispensable. The only way you ever even consider trading him is a situation where in return we get Giannis on a 4-5 year contract in 2020.
Tatum and Brown are both exceptional number twos already, and there is a chance that Tatum will develop into the next Durant, so you do not trade Tatum under any circumstance, even if it means Giannis for 4-5 years.
Kemba is one of the most popular individuals among the league’s players, and he was our marquee free agent last year. You do not trade him under any circumstances in 2020-2022 due to the damage it would do to our brand among future free agents.
Everyone else, including Jaylen, are tradable in multiple scenarios. Mind you, I’d only include Jaylen in a trade for Giannis (100%), Kawhi (100%), maybe Harden (50%), definitely Doncic (but dream on), definitely Embiid (but dream on), definitely Jokic (but dream on), definitely Murray (but dream on), definitely Mitchell (but dream on), maybe Zion (99% but seems incredibly unlikely), and that’s about it.
So the way I see it, there are two players we could maybe get via trading Brown this offseason: Giannis and Harden. Kawhi and Zion are long shots to demand a trade, but not 100% definite they could not be had for Brown, Langford and six first-round picks. If you get Kawhi onboard with being a Celtic, you do it. Zion would be high-risk/high-reward (could become an injury bust, albeit on a cost-controller contract, but could also become the next LeBron). That’s it. Would definitely pull the trigger on Giannis and Kawhi; almost surely take Zion; most likely pass on Harden.
