While I do like Treadwell, and love his competitiveness (he's a very good blocker, BTW)
The strength's that I have highlighted below will always make me want that WR to be a Cowboy. He is a natural born football player.
His makeup is exactly what you want.
______________________________________________
STRENGTHS: Well-built for the position with a muscular upper body and sleek definition. Long arms and large hands to create a very large catching radius.
Natural plucker with vacuum hands away from his body, snatching anything in his general direction. Outstanding on 50/50 balls, showing above average body control and hand-eye coordination.
Lacks sprinter speed, but faster than expected due to strong, decisive strides,
never playing hesitant. Shows the ability to push routes, sink and quickly locate the football.
Plays with grown man strength to brush off tackle attempts and get every yard possible - rarely phased by initial tackler in college due to his balance and power.
Has run-after-catch ability with his strength and athleticism, stretching screens into big gains. Won't allow defenders to chase him out of bounds.
Takes pride in his blocking, throwing his body and overwhelming defenders.
Very strong-minded competitor and doesn't shrink under bright lights. Innately motivated and wired right for professional football. Carries himself like a leader with a goal-oriented mind-set - genuinely enjoys the comradery with his teammates. Very grounded, mature personality for his age and handled adversity well after his 2014 season-ending injury.
