McQuaid, a 6-foot-5 guard out of Duncanville (Tex.) made his decision official shortly after an unofficial visit to the SMU campus. This was his second trip to SMU in the past month.
"I chose SMU because Larry Brown is a really good coach," McQuaid told Scout.com. "I feel like he could develop me a lot better. It's close to home and it's a really good school to go."
"The program is moving in a good direction," McQuaid added. "I just broke it down with my dad a couple weeks ago and it just felt like the right decision."
Larry Brown and his staff evaluated McQuaid, who plays with Team Texas Elite in the spring and summer, multiple times, including the last weekend in April at the EYBL Sacramento event.
"It played a big impact," McQuaid said about his relationship with Brown and assistant Ulric Maligi. "Every coach has seen me play. Ulric and coach Brown came to a lot of my high school games and AAU games."
One of the better shooters in the 2014 class, McQuaid has impressive range on his jump shot and is gaining confidence going off the dribble for mid-range pull-ups and drives to the rim.
"I feel like it's a good fit," he said. "He knows how to get his shooters open. I feel like they will be really good. They get up and down the court. They are guard oriented and have good big men."
Currently regarded as a four-star recruit, McQuaid is ranked No. 69 overall and No. 12 at the small forward position.
Brown now has commitments from a pair of juniors. McQuaid joins Scout.com's No. 23 point guard Sedarick Barefield to make up their current 2015 recruiting class.
