Long and lean, Parker is a three-year starter with inside/outside coverage experience. He lacks top-end speed but rarely finds himself getting left behind by route separation as he plays fast and with good foot agility to match route breaks. He's well-versed in press man and zone coverages. He uses his anticipation and eye discipline to pounce quickly on throws from off coverages. While Parker has good ball skills and a ball-hawking demeanor, he might lack the burst and length to make enough plays on the ball at the next level. He's fearless and tough when it's time to tackle but his slender frame could take a beating as a pro run defender. Parker wasn't a big tester at his pro day, but he knows how to play and could become a factor in camp competition for a nickel spot.
