While your rating of Tune is higher than I have been posting, I do believe it is possible. This doesn't appear to be a great QB class and I feel he does a lot of things well enough to go that high
You have Dell higher than I thought you would - hopefully he shows well this weekend at the combine
You seem to be missing Gervarrius Owens at Safety though. He was at the Shrine Bowl and earned himself a combine invite. I am interested to see how he tests out versus the other safeties on the board
Clayton Tune QB Houston
Strengths: Above average arm strength, not elite, but can make the throws required to in the NFL. Very good accuracy and ball placement. Eats up seam routes and will make defenses pay. Good decision making and ability to look off defenses and get to second and third reads. Will stand in the face of pressure and throw a decent ball but does have enough athleticism to evade and escape if need be. I predict a 4.7 forty time. Got better every year and has a lot of college experience.
Weaknesses: Good but not great arm strength. Will not get away with some of the throws he did in college. Sloppy footwork and will really need to tighten up in the NFL. Will need to learn to take snaps under center. Adjustment to NFL might take a season or two.
NFL Comparison: Kenny Pickett
Tank Dell WR Houston
Strengths: Excellent short area quickness and transition to long speed. Elusive and able to make guys miss using his feet. Dangerous with the ball in his hands. A threat to take it all the way every play. Routes are very crisp and precise. Very good speed and I predict he is a sub 4.4 guy. Dangerous return man.
Weaknesses: Vastly undersized. Probably only a slot receiver in the NFL. Not great hands and will drop some catchable balls. Not going to catch a lot of contested passes. Runs routes well but limited route tree.
NFL Comparison: Marquise Brown
Gervarrius Owens S Houston
Strengths: Good sized safety. Has enough speed to play in the NFL but not much more than that. Decent in coverage and shows good eyes and instincts. Hot motor and hustles to the ball.
Weaknesses: Probably a 4.65+ kind of guy. Hands are definitely DB hands. Takes some really poor angles and misses too many tackles. Probably a depth guy who might be able to show versatility and special teams ability to make a team. UDFA
NFL Comparison: Jordan Dangerfield
