Christian McCaffrey or Alvin Kamara ???

Not really, Marshall Faulk blazed that trail years before RB played a down in the NFL.....I think the way CSP used him was "trailblazing" a bit......in the satellite role.....he used AK in a similar fashion.....

I don't think the number of receptions are the factor, plenty of RB's caught 70+ passes prior to RB.....it's the alignment all over the field that was different and that was CSP.....
That’s what i meant really. It wasn’t really the touches that made him different it was the way he was motioned out of the backfield to create favorable matchups. Not just matchups for himself but for everyone else too.
