IRVING, Texas - The Cowboys are always looking to churn the bottom of the roster, thus Tuesday's signing of wide receiver A.J. Jenkins, the former 49ers first-rounder. But the top of the roster is vastly more important, and that's where the biggest stories are inside Valley Ranch.
Those stories include: The healthy return to the field of Sean Lee, the standout linebacker who missed all of last season after injuring a knee at these same OTAs; the development of rookies Byron Jones, Randy Gregory and La'El Collins; and maybe most importantly, the grabbing of the brass ring by running back Joe Randle, being given the first shot at replacing the departed rushing champ DeMarco Murray.
Of course, wide receiver is also a storyline -- but that's about Dez Bryant, franchise-tagged and without a contract and therefore expected to stay away from these workouts. In his stead, coaches believe Devin Street can excel alongside Terrance Williams. Cole Beasley remains a constant in the slot. Undrafted rookies like George Farmer are in play ... and now too so is Jenkins, the speedster who is just 25 but who has yet to produce in stints with San Francisco and Kansas City and is largely a "camp body'' at this point.
