What It Means:

Former NFL coach Gruden, the face of "Gruden's QB Camp", has a good eye for quarterbacks, and he likes what he's seen out of the Titans' second overall selection. “You saw him turn the ball over against Atlanta, a couple times I think.... And then you saw him string together some really good football. I saw him fall way behind on the road at Kansas City, then he hung in there and engineered a couple of really good drives."

Mental toughness has been the big question on Mariota since he came out of college. With him flashing that tool, there's no reason to think our passing projection on him this year -- 3,700 yards, 22 touchdowns, 19 interceptions -- aren't more than doable for the rookie. We know he has the physical ability to make our rushing projections -- 252 yards and 2 touchdowns -- look silly at any moment. He's a high-upside option at QB21.
