It's not even close if we want to draw a real comparison.
Fred Jackson was a force in some of his prime seasons. Body size completely different. Fred was not the same pass catcher either that ty is.
Honestly I feel like he has his own story to make ( Ty Johnson).
Fred was criminally robbed to not be able to play for a better bills team.
It's a shallow comparison just because they both sat behind someone.
You can compare him to a lot of players across a lot of positions if we are going to make the criteria like that. ( Smaller sample size better numbers not as notable)
