The worst team in the NFL (by a sizable margin, at the time) got rid of Minkah last year. Should we judge Bell based on what other teams were willing to pay?
Keep in mind that Minkah and Bell have very different contracts, and any team that traded for Bell (as opposed to waiting for him to be released) would inherit the 2nd largest RB contract in history. Quality of play is not the only factor here.
You are absolutely right about how a team who traded for Bell would have inherited his huge contract. I had a brain fart and his contract had completely slipped my mind when I was making my post. Interesting point that you raise about Minkah. To be honest, I (and probably nobody outside of Dolphins mgmt) never really understood what the hell was going on with that trade. There was clearly a lot going on behind the scenes between Minkah and the Dolphins and it could have been pretty much anything. I definitely agree with you that quality of play is not the only factor here. There is probably more involved than just quality of play in most trades, actually.
KC was an interesting and somewhat surprising (at least to me) landing spot for Bell. Given that Hellaire isn't very big I suppose I could see KC using Bell as an inside the 5 yard line "punch it into the end zone" kind of back. Personally, I don't think Bell has much left in the tank but I will be the first to admit it if he goes in there and lights it up in KC.
