2. Sterling Brown
Ben McLemore might have a bigger market of contenders looking to add his services, or at least he should. He has proven to be one of the best shooters in the league and every single contending team can use more shooting off the bench.
If that market becomes too hot for the Los Angeles Lakers, since they do not have a lot to trade, they could target the store-brand version of McLemore: Sterling Brown. Brown is not quite the player and shooter that McLemore is, but in a limited role in LA, he might actually provide the same level of output.
Brown is shooting insanely to start the season. He is shooting 45.9% from beyond the arc and is a career 35.5% shooter from three. He is not as good as McLemore is in shooting the three-ball but he is a better defender.
Brown is not a lockdown wing defender or anything but he is an above-average defensive wing who could provide valuable minutes at the position. The Lakers could use one more wing, especially if someone like Wesley Matthews or KCP gets in foul trouble in any given night.
The Lakers would be lucky to get McLemore for the mentioned package as there should be other teams pursuing his services. That package would be more than enough for Brown.
He is going to be a free agent after the season anyway and the Rockets are not going to get a ton for a backend rotation player. They would essentially be swapping backend rotation players, with Brown being the more well-rounded player over McKinnie.
That means that Houston would essentially be flipping Brown for a future second and some big man potential in Cacok, which is a fair price.
