He chose not to run at the combine because he wanted more time to prepare after only training for a week and a half in Miami leading up to his on-field workout day in Indianapolis. In the days leading up to the combine, Treadwell said his goal time was in the 4.5-second range, and that is still the time he's aiming for after an additional month of preparation.
Treadwell will also participate in the shuttle run, three-cone drill and possibly broad and vertical jumps -- which he completed at the combine, recording a 33-inch vertical and 9-foot, 9-inch broad jump.
"(I want to) prove to myself that I can get better over a period of time, which I have done," he said Wednesday. "Just give (scouts, coaches and GMs) more to look at honestly. It's another opportunity for me to get better and another opportunity for me to showcase my skills, show my craft and how much better I'm getting week after week."
The SEC's leading wideout has been working with a Pro Football Hall of Fame receiver and said the improvements to his game are already evident.
"I always work on so many things and it shows up," he said. "Drills are definitely easier than they were in previous times. Working with Cris Carter helped me a lot -- catching the ball a certain type of way, stretching my fingers out ... a lot of little techniques that will help my career."
