...etc for playing in an offense that was cutting edge at the time and defenses were years away from catching up. You'd also have to ding Harvey for playing in Anae's offense which used really big offensive lines to feature a power running game to set up the pass or Jamaal for playing in a zone read offense that had defenses 100% focused on stopping Taysom Hill on every play. You'll have to apply that standard of comparison equally and unilaterally.
I think scheme will always be an important ingredient in the recipe of making a GOAT at any position and not something for which they should be dinged.
