2. Different minds of collaboration
When fans see that Ryan Poles has been with the Kansas City Chiefs since 2009, a year after his NFL career ended in 2008, they assume he does not have much experience working with different people from outside that organization. However, the Chiefs have had many facelifts since 2009, and Poles has moved up as regimes have moved on.
Ryan Poles was first hired by Scott Pioli, who was a Bill Belichick front office member with the Patriots. Pioli was around from 2009-12 until John Dorsey took over. Dorsey came from Green Bay and worked under Ron Wolf.
Poles stayed in his role, but before Dorsey left he promoted him. Then, when Brett Veach was promoted, Veach also promoted Poles. Veach came from Philadelphia and worked with Andy Reid directly.
Having experience with three separate regimes that all featured big-time winners is actually a better experience than most GM can boast.
