"I've improved my route-running and strength since last year. In the past, I hadn't always been big on the weights, but I've been putting in the work in the weight room."
"I'm going to play quarterback and slot," said Stewart. "We have three quarterbacks that we'll use. I'll also be at safety and I'm the punter. Our new offense has given us a big shot. We're using the run and shoot. It will be difficult to stop us, because we're going to make outstanding reads.
Stewart, who was recruited by SMU wide receivers coach Jeff Reinebold, has added a handful of offers since his commitment.
"Plenty of schools have kept coming at me," said Stewart. "Louisiana Tech, Tulane, Pittsburgh, Southern Miss and Memphis have all offered. I'm thinking about taking an official to Pitt in week seven - and maybe Memphis.
"I'm going to take an official to SMU. The campus at SMU is incredible. I'm 100% committed to SMU, and I want their fans to know I'll definitely be up there next year."
Reinebold has kept in steady contact with Stewart.
"He talks to me on Facebook and sends me letters," said Stewart. "He shows me the players they've put into the NFL - important facts and stuff I can use."
