Look I'm trying to be gentle here because I loved the guy, but he was slowww...no other way to describe a back who barely cracks 200lbs and runs a 4.66.
As far as the part you disagree on, I think you are talking more stats, where I'm not considering the stats so much. I'm talking about the guys who looked like the most complete RBs to my eyes...for example I'd rank Folston up among some of the better backs we've had, but his stats wouldn't support that. Same with CJ as far as overall stats, and JJ also had his stats hampered by ty often not playing him enough, but to my eyes they look like special RBs. On the flip side Adams stats are real good, but he wasn't anything special imo (other than his open field speed) just a 'good' RB with speed who benefited from some real good blocking and I'd rank him behind a lot of guys others wouldn't agree with.
As far as Denson I just loved the way he played the position in every way. Outside of his stature I really believe if he was a 4.4 guy he woulda been the perfect RB. I give Walker a lot of credit, he did a lot with what he had and milked the most out of his talent level, as he was a lil slower than Denson at a time when the players around him we're a lot faster than when Denson played, but to these eyes (speed out the window) Denson was an all around better RB than Walker and I'm not gonna say by a mile, but it wasn't that close either.
And yes, Walker leaving early was some terrible advise.
