Oregon defensive lineman is poised to become a first-round pick in next week's , perhaps in the top half of the round. But for one NFL scout Desmond King Ii Jersey , there is an alarming three-round gap between Armstead's talent and his production. "Talented and big as hell. He's the one guy I've had a hard time grading. You watch him and you see the talent of a first-round pick. But then he plays like a fourth-round pick," the . Armstead (6-7, 292 pounds) played several positions along the defensive line for the Ducks, and his versatility gives NFL scouts a measure of confidence that if he struggles in one role, he might flourish in another. His lack of production (2.5 sacks in 13 starts last year) has been a of NFL scouts for months, but the a se sment that he plays like a fourth-round pick is a particularly strong condemnation. The scout also compared Armstead to a steady but unspectacular 10-year veteran who has never developed into a star in the sack category: "You know who he reminds of, . He's that kind of player," the scout said. "I don't think he'll ever be a big sack number guy, but he'll play well for you." The Canty comparison is all the more interesting given the scout's fourth-round a se sment of Armstead's play. Canty, entering his 11th NFL season and his third with the , was a of the in 2005. Five of six mock drafts among NFL Media analysts project the to make Armstead the No. 15 overall pick of the draft. The is former general manager Charley Ca serly, who projects Armstead to slip to the with the No. 32 overall pick. *Follow Chase Goodbread on Twitter * . Jake Hansen Jersey
