According to one source who watched practice on Monday, Allen, listed at 6-foot-11 and 243 pounds, looked stronger. It’s an area he’s focused on this offseason. Along with that, Allen recognizes the need to become a more reliable shooter. He’s also worked on his post game — specifically face-up and back-to-the-basket moves. Often reliant on teammates getting looks for him, Allen wants to be able to create more on his own. That would help Cleveland’s 28th-ranked offensive efficiency last season — a continuation of the post-LeBron James organizational struggles.
