Scouts and GMs are in the business of projecting college players for the NFL. Production and success is considered, but what matters more are traits, skills, and talents.
Floyd has some rare qualities and skills that give him a chance to be a pretty good pass rusher in the NFL. He was miscast as a linebacker at Georgia, but when he rushed the passer he showed a lot of innate ability for it. Had he been used as a pure pass rusher all along he probably would have been a top ten pick from the get go.
