The best part about NBA Summer League is watching players attack new roles. It allows onlookers to reimagine those players.Forget good or bad, efficient or inefficient. The context in Las Vegas does not allow for that. However, watching players start to emphasize a different part of their game, thus shifting what they could bring to a team in the fall and winter, is how things get interesting.Alas, Collin Murray-Boyles and Alijah Martin missed the tournament with finger and knee injuries, respectively. It’s a bummer, especially given the way the Raptors and Murray-Boyles talked about expanding his game. It would have been more disappointing to see either do more damage to their offseasons, obviously, but both absences were minor developmental hits.With those two out, the Raptors were left to largely worry about non-roster players, some of whom could fight for a two-way spot — save for one player, who could be a factor sooner than we previously thought.Allen Graves, forwardThe Raptors’ first-round pick had a nice start to his career. With Murray-Boyles and Martin unavailable, Graves became the focal point of the team. That doesn’t mean the Raptors ran everything through a player who was a sixth man for a mid-major school last year, but there were more opportunities for Graves to stretch.How the numbers helped Allen Graves become an NBA Draft prospectMatthew HoThe numbers speak for themselves: 16.8 points, 6.8 rebounds, 3.0 assists and 2.3 steals per game in four appearances. Graves shouldn’t be the handler in many two-man games in his rookie season, but he wasn’t out of place doing so in this setting. More than that, he looked like a Raptors wing, moving the ball when a quick shot wasn’t there, crashing the glass and switching ably.His lack of athleticism could be a problem when trying to finish plays, but he had a nice start from deep, hitting 11 of 22 3-pointers. The Raptors need to find shooting wherever they can. If Graves’ shot holds up in real games, it will be tough to keep him off the floor, even if he starts in a smaller role.Seth Lundy, wingLundy had a nice rookie season in the G League in 2023-24, putting up gaudy numbers in the Atlanta Hawks organization. Then he missed two seasons because of an ankle injury. At 26, it is time for him to find an NBA home or go overseas.He wound up on a team that needs scoring and shooting, and led the Raptors, averaging 20 points per game. He was so good that he got the “we’ve seen enough” treatment in the last game of the event, with the Raptors sitting him Sunday against the Denver Nuggets.The Raptors already have a 3-point specialist on the roster in Jamison Battle. Lundy got off 32 3s in Vegas, hitting 14. His numbers in the G League and at Penn State say it wasn’t a fluke. Plus, he has always rebounded well for his position.Between needing to fill one more main roster spot and having another two-way spot to work with (assuming the Kawhi Leonard trade goes through), the Raptors likely need to find a spot for a more traditional centre. But so long as the Raptors feel good about Lundy’s health, he did enough to stick around until training camp, at the very least.Nate Bittle and Jamarion Sharp, centresBittle signed an Exhibit-10 contract before summer league, giving him a bit of extra cash if he sticks with Raptors 905, assuming he is waived in training camp. Sharp, the reigning G League Defensive Player of the Year, came in just trying to make an impression.Both did. Bittle has a whiff of a 3, and that is huge for any centre who might play next to Scottie Barnes. He went undrafted out of Oregon, and his speed will be tested defensively. But he was a reliable outlet for the Raptors’ attackers and clearly knew his assignment.Sharp would be a play for a type of centre the Raptors haven’t had in their rotation since … Lucas Nogueira? (Bebe forever.) Sharp dunks, blocks shots and rebounds as a rim-running big man who you want hanging by the rim defensively. He had 14 blocks in five games.You wonder how the presence of a big like Sharp would help Jamal Shead, who has struggled to score in the in-between spots on the floor. However, Sharp’s player type generally excels when surrounded by shooting, and that’s a framework the Raptors cannot offer.Chucky Hepburn and Jaden Bradley, guardsThis was Hepburn’s first competitive games since tearing a meniscus last January. Bradley, meanwhile, was still getting used to the Raptors after a grind of a pre-draft schedule. The Raptors took him late in the second round. Both are on two-way contracts.Neither had a good offensive tournament, although Hepburn had a 13-to-4 assist-to-turnover ratio in the two games he played before soreness in his surgically repaired knee sent him to the bench. Hopefully, this was pure discretion on the Raptors’ part, because Hepburn sure looks like a Shead clone — a good decision-maker who is pesky on the ball.That is also what the Raptors are hoping Bradley will become, although you could see who spent a year in the organization and who was new in Las Vegas. Bradley got to the free-throw line 15 times, but he has a way to go elsewhere to get ready for the Raptors. Pencil him in for a lot of minutes in Mississauga this year.
