Some of the scouting reports on Davis were that he has inconsistent hands.

est 40 receptions, 672 yards and 2 TDs as a senior. Athletic receiver prospect with an inconsistent game. Uses the sidelines well, nicely adjusts to the errant throw and plays heads-up football. Consistently extends to make the reception away from his frame. Competitive, keeps the play in bounds and always working to pick up positive yardage.
Negative: Does not display consistent hands, does not always come away with the difficult reception and has throws bouncing off his hands. Must improve his route running.
Analysis: Davis is a talented prospect who's slowly turning his athletic ability into football skill. His return skills could help him catch hold of a roster spot where he'll also lineup as a 5th receiver.
That does not jive with reports of him at Combine and Senior Bowl where he caught the ball really well. Of course, it's one thing to catch balls in drills, and another thing to do it in a game. He can really add something though to the offense with his speed. The addition of him and Jared Cook, as well as the return of Jordy should give the Packers the ability to stretch the field.
