Here's his scouting report from Geoff:
The SMU secondary took a substantial step forward in 2016. Catapulted by an increased in turnovers, the defense was held together by the secondary, which was essentially a liability just a year earlier.
SMU offered on Monday a scholarship to Colleyville Heritage (Colleyville High School) cornerback Marcus Mosley, a member of the class of 2018. Mosley seems to be a perfect fit for SMU’s aggressive approach to defending the pass, reeling in seven picks in 2016.
Mosley’s hands are his best asset. With experience at wide receiver, clearly his hands have been tested before. He displays an ability to catch on the run and make plays on the ball on his highlight film, reeling in balls over his shoulder and in traffic. Jumping routes is a calculated risk, but Mosley shows good instincts when reading routes.
Mosley has also spent time as a safety where he can disrupt deeper routes. He will most likely be used in run stopping situations if he plays any safety at the next level because his strength is defending in the air.
