Whisenhunt said the Cards will try multiple people at kickoff returner in an effort to replace the departed J.J. Arrington, and that includes Wells. …

Tight end Dominique Byrd has shown he can catch the ball, Whisenhunt said, but it will be Byrd’s blocking that will ultimately determine if Byrd can find a role on the roster. That can’t happen until training camp, Whisenhunt added. Byrd could also possibly be worked in as a fullback/H-back, Whisenhunt added, but again, it will hinge on an ability to block.

This is promising news to hear about Byrd who was an invitee to mini camp, who ended up signing a one year offer. If he is a consistant blocker he may be able to become an additional threat if used in three different positions on the already high flying offense. Byrd's chance of securing a roster spot seems to hinge on his abillity to block.
