Most of the newcomers have some connection to players already on the team.
Defensive back Marcus Cooper and wide receiver Chad Hall, waived by the 49ers, had been worked with wide receiver A.J. Jenkins, whom the Chiefs acquired in a trade a couple weeks ago. Then there's linebacker Dezman Moses, waived by the Packers,Vans Old Skool Usa Sale, who spent last season playing alongside Frank Zombo, who was signed as a free agent and managed to survive the roster cuts.
