Colleges are recruiting McManis for both positions.
"My weakness would probably be my speed," he said. "I need to work on my speed a little bit more. My strengths, good tackling. I know how to read (defenses). I cover pretty well. But like I said, my speed is something I need to work on."
Numerous schools have shown interest in extending McManis a scholarship offer. However, his only offer thus far is from Memphis. "It's not too far from home and they've been showing a lot of interest," he said of Memphis.
Mostly, though, he is under evaluation. Ole Miss, Arkansas, Mississippi State and Southern Miss are among the many schools checking in.
The 6-foot-1, 200-pound McManis was in Oxford for Ole Miss' elite camp earlier this month. He worked out primarily with the linebackers, running a 4.88 40-yard dash and recording a 31-inch vertical jump.
He is being recruited by wide receivers coach Gunter Brewer, who McManis said has been advising him on the areas of his game he needs to work on to earn an offer. But the Ole Miss coaching staff likes him, he said.
They just have to see more.
"I've been coming to Ole Miss for a while. They started talking to me after I began going to these camps," he said. "They came down to visit me, then they started coming to my practices in the spring. From then on, we've just been talking a lot more."
He said Mississippi State, UT-Chattanooga and Southern Miss are closest to offering. And should any of those schools pull the trigger soon, they would immediately move up his pecking order.
"My interest would certainly go up with those schools if they were to offer me," McManis said. "Then it would just go to playing time and how many other people they're recruiting at my position and stuff like that. I do understand that I'm going to be a freshman coming in, but playing time will be a factor."
As to a timetable for his decision, well, McManis isn't sure yet.
"It depends on how the camps and things go," he said. "If I do get these offers, I would like to make a decision probably before the season."
