You’re right. The 23 year old RB who missed 1 game last season because he was still on the practice squad, only started for 12 games, and had still 973/6 on the ground on an offense that ranked 27th in total yards sucks. Seems like a well thought out point of view.
As for Graham, he was 4th on the team in yards behind Baldwin (expected), Richardson (surprising), and Lockett (embarrassing). He is a TD threat, no doubt about it, but GB has superior talents at WR and RB for pass catching. Jimmy will likely only be a TD guy. TE premium really amps up the value of the elite TEs, Graham is no longer one of those in terms of his production. I could see him posting the exact same line this season, maybe 100 more yards max. I’d rather have the RB due to positional scarcity rather than TEs made artificially scarce by scoring settings that don’t actually increase most of their values that much
