While Mariota widely impressed coaches this spring, Green-Beckham spent weeks sidelined by a hamstring injury. That aside, his former college coach believes the Titans have landed the equivalent of a "nightmare matchup for any cornerback at any level."
Norvell spent last season coaching the red-shirted Green-Beckham in practice at Oklahoma, saying: "When you go through the history of the draft and look at the guys with size and speed and all that, he is just unique. Calvin Johnson is probably one of the closest comparisons physically because of his size."
"He's not a finished product, but most players aren't," Norvell said. "So he's going to have to learn the pro game and that's a completely different game from college. But he's got some natural gifts that will help him in that game, and in some ways, the NFL is probably a better game for him than college football, just because of the bump rules and (less) contact and all of that. So there are some advantages he has. ... That's why they picked him."
