Looks about right... I did see a report yesterday that Kiper has Litton as one of his "players with the most to gain" at the combine. Said he could move up from a late-round selection, maybe as high as the third round, with a good showing.
It's interesting that Litton is ranked as the 15th best QB by the NFL scouts with a 4.9 grade... Also interesting that Sam Darnold got a 7.1 grade, which is a full point better than the next guy (Josh Rosen, 6.1).
Darnold, USC – 7.1
Rosen, UCLA – 6.1
Mayfield, Oklahoma – 6.0
Jackson, Louisville – 6.0
Allen, Wyoming – 5.9
Rudolph, Oklahoma State – 5.6
Falk, Washington – 5.6
White, Western Kentucky – 5.6
Lualetta, Richmond – 5.1
Ferguson, Memphis – 5.1
Benkert, Virginia – 5.1
Briscoe, Sam Houston St. – 5.0
Flowers, South Florida – 5.0
Tanner, Nebraska – 5.0
Litton, Marshall – 4.9
