The Mavericks acquired the rights to Sergio de Larrea in a trade during last month’s draft. “He’s come in from day one with a great understanding of who he is,” said Summer League coach Joe Boylan. I think he’s going to bring that to any game he plays. Whether or not de Larrea can be a rotation player as a rookie may depend on how he quickly can shore up some of his improvement areas, Clark notes. Those will be points of emphasis we continue to work on in the summertime.”
