As part of the three-team deal that sent point guard Brandon Knight to the Phoenix Suns and brought Michael Carter-Williams to Milwaukee, the Bucks shipped injured guard Kendall Marshall to Phoenix in order to clear a roster spot. Milwaukee also acquired Tyler Ennis and Miles Plumlee in the three-for-one deal. With Knight and Marshall outgoing and a buyout of Larry Sanders expected to be finalized soon, the Bucks will be back to a 15-man roster. Marshall is currently recovering from a torn ACL suffered on January 15.
Marshall appeared in 28 games for the Bucks, averaging under 15 minutes per game, but had good per-minute numbers and was starting to claim a larger role on the team prior to his injury.
While it's very early to speculate on what might happen in the coming offseason, it's worth noting that Milwaukee can re-sign Marshall, who will be an unrestricted free agent, beginning on July 1st. However, with Carter-Williams, Ennis, and Jerryd Bayless all under contract for next season, the Bucks may have no need for anther point guard.
