"I feel like it's more complex in the mind too. For me, I like beating people mentally before physically."

Isaiah Johnson used to play wide receiver for the Houston Cougars and halfway through his career he found his true football calling. Switching from catching passes to defending them, Johnson sets his sights and mind on the NFL.

"I personally like corner better," Johnson said at the NFL Scouting Combine over the weekend. "You know everybody has their different likes. For me, corner is better because I like to compete and I feel like it's more fun to stop somebody from doing something they want to do rather than me just going and trying to do something."

All he does is dissect film. He takes it home with him on his tablet. Even makes a special trip to the football facility to watch it on the big screen. He enjoys it and knows it is a necessity.

"I was a big film study guy," he said. "So I studied formations studied route concepts - studied what people do and how they like to do it and that was a big thing for me especially in the fast conference that we had to you have to dissect and learn so fast what other people are doing to get a jump on it. I had to study and make sure I knew they were going to do before it happened."

Don't let the smarts fool you, he isn't all brains. Standing six feet two inches tall and weighing in at 208 pounds Johnson skews towards the high end of height-weight at the position. Teams like his physical stature.

"They love my length," he said. "They love my ability to come up and tackle. They love my ability to cover."

He's not through growing at corner either.

"Just because I played the position for two years they know I have a higher ceiling than where I'm at right now. They feel like I can fit into multiple schemes. They just really want to see what I can do and see my max potential that way they know how I fit in their scheme."

While the NFL career is just starting, the 2018 Human Resources and Development major already knows what he'd like to do when he finishes up beating NFL wideouts physically and mentally.

""Actually after doing this and just experiencing the real world and seeing how things are I'd rather get into coaching," he said. "Just to affect the future generation try to help them find the love for the game all over again."

We know coach Johnson is going to be a great one in the film room.
