Some expect Broncos RB Laurence Maroney to surpass Correll Buckhalter and become Knowshon Moreno's primary backup in short order, but head coach Josh McDaniels considers Maroney to be his third back for now and word is there may not be a depth-chart shuffle anytime soon. While Buckhalter looked more explosive than Moreno for much of last season, he will turn 32 in October and his body has sustained plenty of wear and tear. The Broncos view Maroney, who has struggled with injuries and inconsistent play throughout his career, as a player with a brighter future. His contract will expire after the season, but word is GM Brian Xanders wants to re-sign him. McDaniels coached Maroney in New England and has an affinity for the fifth-year back. The Broncos feel more secure with him as a third option than they did when Lance Ball, an undrafted player with 13 career carries, was serving in that capacity prior to the trade.
