"Speed always brings a different dynamic but overall it has to fit into the construct of the offense," GM Monti Ossenfort said at the recent NFL owners meetings. "Sometimes some of those speed receivers, they don't check off all those boxes. Speed is great, no question. But it can't just be speed. It can't just be a one-trick pony."
The Cardinals do have players on the roster that can play the role. Xavier Weaver made the roster as an undrafted rookie last season, although he was only active for a couple of games. Greg Dortch hasn't really been used much as a deep threat, even if he could. Former Eagles receiver Quez Watkins was signed in part for his downfield possibilities.
Suggesting Marvin Harrison Jr. or Michael Wilson wouldn't or won't be used downfield isn't factual either, although their straight-line speed isn't high on their resumé. What is, however, is many other things important to Gannon and the coaching staff.
