IRVING, Texas -- One way to get better in any business is to weaken the competition.
Dallas Cowboys coach Jason Garrett hired Green Bay wide receivers coach Jimmy Robinson as assistant head coach/wide receivers coach on Friday, less than a week after the Packers won Super Bowl XLV at Cowboys Stadium.
Robinson, who has been in the NFL since 1990, replaces Ray Sherman. Sherman coached the Cowboys' wide receivers from 2007-10 and interviewed for the head coaching position that went to Garrett after the season. Sherman was quickly informed he would not be retained in 2011.
The Cowboys also finalized the hiring of Mike Woicik as the strength and conditioning coach. Woicik spent the last 11 seasons in New England, winning three Super Bowls, after winning three in his tenure with the Cowboys from 1990 to '96.
Garrett and Robinson were together with the New York Giants in 2000-03, when Garrett was the backup quarterback and Robinson was the wide receivers coach. Through the years Robinson has coached some of the NFL's best receivers, including Indianapolis' Marvin Harrison, the Giants' Amani Toomer and New Orleans' Joe Horn. He has been with the Packers since 2006, helping in the development of Donald Driver, Greg Jennings, James Jones and Jordy Nelson.
With the Cowboys, he inherits Miles Austin, who has played in the last two Pro Bowls, Dez Bryant, who had his rookie season cut short by a fractured ankle, and Roy Williams (at least for now) as the top three wideouts.
With Friday's hires, Garrett has added six coaches to his staff since the season ended. Rob Ryan was named the defensive coordinator and brought linebackers coach Matt Eberflus and defensive assistant Ben Bloom with him from Cleveland. Brian Baker was named the defensive line coach earlier in the week.
