IRVING, Texas -- The pre-draft process was frustrating for Jamar Wall.

Wall injured his hamstring while working out before the combine and couldn't participate in any drills there. He tried to work out for scouts at Texas Tech's pro day in March but pulled his hamstring again while running the 40.

"You can't even explain it in words," said Wall, who added that he has fully recovered and will be ready for next weekend's rookie minicamp. "I know I could have proven myself to teams."

Not that Wall would have wowed any scouts with his 40 time. He calls himself "more quick than fast." His last timed 40, which was run at Tech's pro day for juniors last year, was a 4.55.

Wall prides himself on being a physical, smart player who knows how to adjust to opposing receivers.

"I have great game speed," Wall said, and he looks forward to proving it during the preseason.
