Last night, Marks identified Pettway as a big target for the Mustangs.
"Coach Klemm is a great recruiter and a great coach, and we're going to have one of the best classes you'll ever see if he's able to get all the guys he wants," said Marks. "We'll have Robert Lewis, who I know well, and I hope to persuade Raymond Ford, the corner from Serra, to commit.
"Also, I want to get linebacker Khalil Pettway, who is definitely underrated. I work out with him every Sunday. He's so athletic as a middle linebacker. He's going to be a late bloomer."
A couple of weeks ago, Pettway traveled to the Hilltop, and Scout.com's Ashley Swafford got his reaction.
"I went to SMU when I went to play in the Badger Sport's National 7v7 Tournament in Dallas last week," said Pettway to Swafford. "I took a tour with some players and coaches and really liked it. I liked the community, class sizes, and their notable history of winning. The only thing I really didn't care for was the weather, but that is something I could get used to."
Last year, Pettway helped Culver City to a 6-5 mark. He was among the team leaders with 64 tackles (34 solo). He also notched three sacks.
In week five, Pettway's squad dropped a 42-22 decision to Narbonne and current SMU freshman Dontae Levingston.
SMU has collected four commitments this month, including three from the Golden State. Kache Palacio (Gardena Serra) was the third from California. Texarkana (Tx.) DT Nick Reed rounds out the quartet of July pledges.
