​Brad Stevens has endured a busy offseason so far, with moves ranging from trading Jaylen Brown to the Philadelphia 76ers to signing Mitchell Robinson to a three-year deal using the full non-taxpayer mid-level-exception. There’s no denying that Joe Mazzulla’s rotation is going to look very different by the time the new NBA season gets underway.However, adding new faces hasn’t been the only thing Stevens has done this summer. He’s also started locking down some of Boston’s younger players to longer-term stays with the franchise. Neemias Queta has already inked a four-year $56 million extension, and on Thursday, July 23, Boston announced that they’d tied Jordan Walsh down to a three-year $15 million deal.With the news of Walsh’s extension fresh in their mind, Adam Taylor, Tim Sheils and Mike Weber discussed how Boston’s developmental pipeline is emerging as arguably the best in the NBA. Both Queta and Walsh began their developmental journey in Boston on two-way contracts, and now join Sam Hauser as success stories on the main roster. Luke Kornet, who won a championship with Boston before earning a payday with the San Antonio Spurs, also spent time in the Celtics’ developmental system before making the step up to their main rotation.During the episode, the trio also discussed the areas of growth Boston will need to see from Walsh in order for him to earn a bigger role within the rotation, and why Walsh’s new contract sits firmly within the “tradable range” should Stevens look to take a bigger swing down the line.You can listen to the full podcast episode by clicking on the embedded player above, or clicking one of the links below.
