Temple's Robby Anderson is 6'3" and ran a 4.34 40 at his Pro Day.
Between he and the 7th rounder from Clemson we might get lucky with one of the two prospects.
From NFL.com:

40-yard dash: 4.34 seconds
Vertical: 36 1/2 inches
Broad jump: 10 feet, 8 inches
Short shuttle: 4.28 seconds
3-cone: 7.07 seconds
Bench: 8 reps of 225 pounds
STRENGTHS
Has tremendous bounce to climb the ladder and snatch the pass at its high point. Has excellent balance and body control to make the circus catch. Plays faster than his timed speed and has decent short area quickness. Well-liked by coaching staff and considered a good teammate. Showed ability to get some separation during Shrine Game practices.
WEAKNESSES
Rail-thin frame. Missed 2014 season after being suspended for academic purposes and elements of his game fell off in 2015. No such things as easy catches. Able to make the circus catch, but struggled badly with focus drops. Average long speed and getting deep on double moves and through play*-action.
DRAFT PROJECTION
Rounds 6 or 7
BOTTOM LINE
Tall, but rail thin with a 2015 season that featured Anderson's ability to make the incredible catch sandwiched with way too many drops. His separation quickness and overall speed doesn't jump off the tape, so he needs an impressive combine.
