Disclaimer; My apologies in advance if someone already wrote him up. As managing editor of Miami's SBN Blog, State of the U, I have got the chance to see this young man more then I would have liked.
On Tuesday's conference call, NFL Network's Mike Mayock made a comparison between Joyner and Tyrann Mathieu. One small difference between the two that Mayock failed to point out: You get all the same talent with out any of the off the field headaches.
What does he bring on the field? Well as a 1st team All American and the undisputed leader of a National Championship defense, a whole lot.
He is a heat seeking missile that hits like a LB and covers like a CB.
Did a fantastic job blitzing off the corner, and produced 5.5 sacks (most in the NCAA among DB's), 7.0 tackles for loss, forced 3 fumbles, and registered 69 tackles overall this past season.
Also picked off two passes. Not bad considering most ACC QB's were probably instructed to find and avoid him pre-snap.
Through out his career he has shifted between CB and S for the Seminoles and shows the ability to play bigger then his size (5-8 190) when supporting the run, and is quick enough and heady enough to cover bigger receivers on the outside as well as inside slot receivers.
Projects as a S or Nickel on the next level, but could probably fill in at corner in a pinch. Is a big time time hitter that can also immediately upgrade any team's special teams as well.
Projects as a 2nd round pick, runs a 4.5 40.
Breaking Joyner down further:
Strengths: Sure tackler, outstanding ball skills, great leader, versatile in coverage, hard to block, phenomenal blitzer. Smart football player who can pick up schemes. Has been a winner since H.S. (St Thomas Aquinas).
Weaknesses: Perhaps a bit overaggressive at times? Size if you are into nitpicking.
Summary: Whoever gets this kid is going to immediately upgrade their defense. Whether he covers the slot, plays in the box, or on the outside, he is a flat out playmaker. Despite where he went to school, easily one of my favorite players in this draft. I see Joyner as a perfect fit for the Jets. When your biggest weakness is aggression and you have the penchant for creating turnovers this guy does, you are built for a Rex Ryan defense. Anyone who watched the Clemson game knows that Joyner as much as anyone including Jameis Winston was the biggest reason they routed the Tigers. IMHO this guy was the best player on the best defense in the country.
