The torch does gets passed. And. I dont have the injuries memorized. But in 2006. Foster had 227 to deangelos 121. And in 2007 foster had 247 to deangelos 144. In 2008 deangelo had 273 and stewart had 185.
Looks to me like he favors the vets over the younger guy in general. And he has a pecking order established.
Part of Fox's tendencies have to do with pass protection. DeAngelo Williams was not good at this early on in his career and I think that limited Fox's confidence in using him more.
The other part is I think Fox just prefers a bigger RB.
Rational coaching Fox would have used WIlliams a lot more and not drafted Johnathan Stewart.
You see the pattern repeat itself somewhat in Denver as well.
John Fox
coaching history. Fox is a defensive minded coach, so he doesn't really influence the the offensive side until he becomes a HC in Carolina. He is from the Bill Parcells coaching tree.
His first primary RB was Lamar Smith who was a featured RB for Miami before signing with the Panthers as a free agent. He is one of the rare RB whos best productivity starts at the age of 30. He had Dee Brown who also had 100 carries in COP role. Nick Goings was a FB/HB tweener who got used when other players were hurt. They also had Hoover who was a more traditional FB with some receiving skills.
2003 they went the free agent route again signing Stephen Davis from Washington at 29 years old. 2nd round pick Foster got 100 carries in COP role.
2004 Davis and Foster get injured and Nick Goings gets 217 carries.
2005 is a fairly even split between Davis and Foster. Davis starts the first 11 games but he isn't very effective and they use Foster more at the end of the season.
2006 Foster gets 227 carries with rookie Williams getting 121.
2007 Foster gets 247 carries (at 3.5ypc) while Williams gets 144 (at 5ypc).
2008 the Panthers do not keep Foster who moves on to SF before exiting the league. The Panthers draft Stewart in the 1st round. Williams gets 273 carries at 5.5 ypc Stewart gets 184.
2009 Stewart gets 221 to Williams 216.
2010 Stewart gets 178 Goodson 103 Williams 87. Williams only played in 6 games and Stewart in 14 games.
2011 with Denver they bring in 30 year old Willis McGahee who gets 249 carries. Moreno was injured or he may have been used more.
2012 McGahee 167 (10 games) Moreno 139 (8 games) Hillman 84.
2013 Moreno 241 rookie Montee Ball 120 Hillman 55
2014 Cj Anderson 179 Hillman 106 Ball 55.
2015 with the Bears Matt Forte was the main RB until he got injured. Then it was a RBBC after he came back, likely because Langford played well enough that they wanted to see more of him, especially after they were out of the playoff hunt.
So there is some preference for veterans and I think also a preference for a bigger RB. You see this pattern with Fox repeatedly. I think Fox wasted a good part of DeAngelo Williams career in part because of not seeing a smaller RB as the guy he wants to lean on.
Howard fits the mold of a Fox RB more than Langford does. I see Langford being the COP to Howard if things go how Fox wants them to.
