FWIW, I read over on BTSC that he's thought to be the second fastest guy on the team behind Archer. In another article he stated that scouts at his pro day told him they had him at 4.28 in the 40, but that NFL Network reported it as 4.4 official. If he actually has that kind of speed, and if he has any potential, hopefully he ends up pushing Archer in the long run.
Now, before anyone decides to jump in and "reconstitute" my words, I'm not saying that I expect an undrafted FA to take Archer's spot, that it will be easy for him to do so, or that Archer is a bust. Just that with luck, he will push Archer as competition would hopefully bring out the best in both and it would put the team in a better position.
