I think that's some bad framing. He had one team under a different regime that drafted him that saw a chance to upgrade in Gibbs and took it. Philly was interested in retaining him but they preferred to upgrade with Barkley. Almost every single RB in the league right now on their second contract is at least on their second team.
As for having comp a few things to consider. That regime seems to view Herbert the way the current Lions regime viewed Swift. Inherited him, never seemed to warm up to him much which is why Swift was the first person signed in UFA.
Now the touches. Feel like I've beat this death discussing Swift over the years but one of the reasons I find him so valuable is that he's shown he does not need a lot of touches. The Eagles year, where IMO he was not used to the best of his skill set, dragged him down but it's still really good. With the Lions he averaged exactly 13 touches a game and produced 14.85 fantasy points a game which to put in context would be RB14 last year and within a point of RB10. When you factor in the Philly season he's up to 14 touches a game, 10.58 carries and 3.48 receptions and 14.17 fantasy points a game. We'll see in Chicago but early world I heard was his pass catching ability was the big draw, to give Caleb as much easy options as possible, which should lead to higher fantasy points per touch.
Also he's missed an average of 2.5 games a season which is not great but not nearly as bad as people seem to think.
