For hoopers, no matter the level, the summer is the time to get better at your craft. And for NBA players, it’s a time mixed with hard work and vacationing.

Once again, the Celtics will head into the upcoming season with high expectations. With their deep roster, guys who will have to earn every minute on the floor. Staying at the same level is always an easy way to make your way out of the NBA.

Therefore, here’s a list of what each Celtics player needs to work on this summer. I’m not going to mention every single player on the roster, because some aren’t important enough at this point.

Jaylen Brown: Dribbling

This is a no-brainer, back-track to two years ago when the C’s lost to the Warriors in the NBA Finals, Jaylen Brown’s flaws were shown. Brown didn’t have a bag he could get into when it comes to his handle. Unfortunately, the same held true this season. That’s not to say he didn’t get better, he found a way to use less dribbles to get to the basket.

But in order to make that next step in his game, he needs to be able to develop a lethal crossover. More than just a guy who can go by defenders strictly off athleticism. He gave up 197 turnovers this past season, a lot of that was because he lost the ball.

Jayson Tatum: Pacing

This one isn’t much of a set skill that can be worked on every day per say, it’s more of a veteran attribute. This past postseason, we saw Tatum score in bunches by getting hot from deep or finding a mismatch. And although the 30-point scorer is stellar on the offensive floor, he needs to learn pacing.

Pacing was a big reason Kobe Bryant won so much in the back-half of his playing career. He knew when the game was slipping away, so he would go to the basket and attract a foul to stop the clock. Tatum needs to get a pulse on what’s happening in the game and figure out how to impact it even when he’s not scoring. Who’s hot? Who hasn’t gotten a shot off lately? Those are the questions that should be going through his head during a game.

Robert Williams III: Post moves

I’m not going to go off on Robert Williams III, but his offensive bag is invincible. Sure, when he first got to the league, he got by with his high-flying plays and scrapping for boards. But now the Celtics need more from him, hence why they brought in Kristaps Porzingis. And before this season they brought in Danilo Gallinari. The front office knows Williams hasn’t developed a single post move to his repertoire, and that’s a huge issue. You can’t be a shot blocker and lob catcher forever.

Grant Williams: Everything offensively

Rarely did we see Grant Williams get playing time in the playoffs. Part of that can be due to the fact he was battling an injury, but if you ask me, it’s because he hasn’t progressed as much as he should. Teams know he wants to catch-and-shoot on the perimeter and just defend, it worked two years, but the scouting report is now out. Grant needs to learn to drive to the basket, become a better rebounder, and get a better handle or else he’ll find himself on the bench or requesting a trade.

Malcolm Brogdon: Veteran-IQ

Malcolm Brogdon was the Sixth Man of the Year thanks to his 14.9 points a night and 44% from deep. He’s a good offensive player, but now that Marcus Smart is gone, the C’s need more from him. Brogdon is will have to find a way to impact the game in ways more than just scoring. They need a floor general that can defend and assist the ball.

Kristaps Porzingis: Toughness

The only concern I may have for Porzingis is durability and toughness. The former Wizard has little playoff experience and hasn’t played close to 82 games since his rookie season. The C’s need guys who can actually suit and get on the court. And when the playoffs come around, guys play harder and it’s a mental battle as well.
