Crowder has taken multiple steps forward since joining this team. As have Avery, IT and Smart. If he can keep this up, which I think he can, he has a very bright future. He's shown such a wide variety of ways to score in the past couple months, with that on top of his incredible work ethic, it's hard to imagine him regressing much.
He's on a similar trajectory to DeMarre Carroll, albeit with a higher ceiling. He'll likely never develop into a Jimmy Butler type player, but it sure seems like he could manage 18/6/4 on good percentages with elite defense as a starting swing going forward. I'm amazed at his progress so far with us. He's literally 6 months into his first deal (5yr/35M) and it already looks like one of the best contracts in the NBA! For a guy who's like 24 or 25 and obviously still improving. Just imagine how good that contract looks in 2 or 3 years.
He and Smart are the heart and soul of this team, and I'd like them to be the heart and soul of the next great Celtics contender. Crowder, considering all his improvements and increasingly substantial role, might be my favorite post big 3 Celtic so far.
