1. Devin Booker
(Trade Value: A+)
This is an obvious one. Every team in the league wants Devin Booker, which makes him a highly valuable trade asset. Of course the Suns would never trade him (I suppose unless LeBron James demanded a trade to Phoenix and guaranteed two other stars would be joining him) but if Ryan McDonough was to offer him up the bidding war would be tremendous.
Not only is Booker approaching only his third season and has already established himself as a tremendous scorer with the ability to pour on points whenever he needs, but with two full seasons remaining under his rookie contract, a team with a bunch of highly paid stars could add him and remain under the cap fairly easily. If Cleveland, for instance, loses to Golden State in the Finals and wants to add another star, they will first seek talent that is still paid under a rookie-scale contract to be able to fit him under the cap.
Obviously the Suns have zero interest in trading Devin Booker and will not. But the options, if we are honest with ourselves, would be a lot of fun to discuss.
