13. JD Davison
Davison is the third and final player on a two-way contract, and Celtics fans should want to see more of the former second-round pick as he enters Year 2.
It would be surprising if Davison ever developed into a high-volume scorer, but Boston doesn't need him to. He makes his presence felt as a playmaker, and that was on full display when he averaged 7.2 assists, 4.0 rebounds and 1.4 steals in Summer League action.
There's a real chance that Davison could challenge Banton for point guard reps when he's with the team. Davison only played in 12 games at the NBA level in 2022-23, so he didn't really get the chance to show off his abilities, but here's to hoping he gets the opportunity to do so this year.
12. Jordan Walsh
Perhaps the biggest surprise on this list, Walsh lands in the No. 12 spot because he fits seamlessly in the Celtics' system.
Walsh is just 19 years old, and while his defense will likely be what makes him stick out in the long run, he averaged 16.0 points while shooting 40.7 percent from beyond the arc in five Summer League games.
It's easy to get carried away with those numbers, though. Walsh isn't going to come out and be in the Rookie of the Year conversation, nor will he be a rotational centerpiece, but the 38th overall pick of this year's draft has an excellent opportunity to learn under some of the best talent the league has to offer.
11. Luke Kornet
Kornet took on a larger role than anybody expected him to a season ago, averaging 11.7 minutes across 69 games off the bench.
But he isn't a bulldog in the paint or intimidating on the defensive end, where he so often relies on the "Kornet Contest" to distract shooters. Entertaining? Yes. Always effective? Not quite, but still, better than you'd think.
On days where Boston opts to go with a double-big starting lineup, Kornet will end up being the backup center. However, don't count Gabriel out, because he could take over that role somewhere down the line if he starts showing more defensive upside.
