There were questions about the only three Raptors who actually mattered when the summer league season began and now that they’ve endured the spotty officiating and hectic schedule and escaped without anyone suffering any debilitating injury there are questions that remain. Summer league is more about getting through it with some teaching moments taken care of more than anything else and general manager Masai Ujiri is back in Toronto from Las Vegas pleased with what he saw while fully acknowledging there remains significant work to do. Jonas Valanciunas had moments of domination against inferior competition en route to being named the league’s Most Valuable Player Terrence Ross remains enigmatic with more potential than polish and Quincy Acy remains a delightfully hard-working tweener who may or may not have an NBA position. It’s pretty much what the team’s brass and coaching staff expected when the Las Vegas vacation began two weeks ago. Valanciunas was unquestionably the most pleasant surprise he arrived bigger and stronger more capable of adapting to the intricacies of NBA defence and more able to handle the speed of the game. He was the best big man in the 22-team event — even if he was playing against marginal NBA talent — but remains a work in progress. But there was no regression he was better than he had been at the end of last season.
