LAS VEGAS — Caleb Wilson did not need to conjure motivation. Not now.For five months, he’d counted the days until his next chance to prove himself. On Friday night, he scrolled back to look at the picture of himself in a blue hospital gown, sitting up in an inclined bed fresh out of a season-ending thumb surgery, his fist clenched to signal hope.On most days since, Wilson’s lock screen on his phone has been set to a still shot of his stroll off North Carolina’s bus to play Duke, one of the final games of his college career. In his camera roll, all of Wilson’s emotions are there. The hurt, the longing, the ambition, the need for redemption. Everything he wanted his NBA debut to be, what he hoped it would feel like, was always on his mind.“I cried before I played today,” the Chicago Bulls rookie said after tallying 35 points, five boards and three blocks in his Las Vegas Summer League debut, a 97-96 loss to the Memphis Grizzlies. “It’s been five months to the day since the last time I played, and I’ve just been really emotional because I haven’t been able to play. I felt terrible because my team lost in the tournament and my coach got fired. It was a lot for me at that point.“So coming out today, it just felt like I’ve been waiting so long for this opportunity.”Caleb Wilson getting it done on both ends in NBA Summer League debutThe wait was worthwhile. For Wilson, and for Bulls fans who endured a flatlining franchise, Friday felt like an affirmation.As the draft cycle progressed and he was widely considered the fourth-best prospect on the board, Wilson’s looming question mark was 3-point shooting. In his lone season at North Carolina, Wilson attempted 27 3-pointers and made seven of them. He made just as many in his pro debut on 11 attempts.His first shot was an off-the-dribble 3, a nudge toward the defender that sagged off of him for a moment. The tough shotmaking only slowed when the ball stopped being funneled to him. At one point in the third quarter, Wilson drilled three straight 3s, two of them stepbacks.In the back halls of the Thomas & Mack Center, Denver Nuggets forward Peyton Watson intercepted Wilson once he concluded his postgame scrum. Watson relayed what many whispered throughout the gym: none of Wilson’s audacious shots seemed unnatural or awkward.His movements, his decisiveness, his release. Nothing looked out of character, even if his college sample determined it was. For a Bulls offense dying for everything Wilson provided, nothing felt out of pocket. Wilson was such a dominant inside-the-arc force that UNC never cared to waste his attempts on the perimeter. His volume, and even the absurd shotmaking, felt like an outlier Friday. His belief didn’t.
