Harris is a tremendous athlete who has great speed and quickness. Where some prospects need time to build into their speed, Harris has the sudden ability to explode from the jump.
As a quarterback, he displays solid vision to read defenses. Harris is quick with his drops, plus he doesn't waste much time when setting his feet in the pocket. He has good arm strength, but Harris is at his best when his timing and rhythm are in sync with his receivers, as that's when his accuracy is nearly exceptional.
Blessed with natural mobility and athleticism, he has no issues attacking the edges to make throws on the run. If things break down in the pocket, Harris can easily escape rushers to make dazzling plays with his legs.
If he doesn't play quarterback at Florida State, Harris still projects to have success as a receiver, cornerback or safety. Also, look for him to offer his services as a returner on special teams.
