You have to give TT credit for Collins as an impact player. Possibly Finley, had he stayed healthy. Sitton, for as much as a guard can be an impact player. Lang is close, for as much as a guard can be. Lacy was very much an impact player as a rookie when he carried a lot of the offense with Rodgers out, I'm not sure what he is now. As a second/third year player, Bulaga was being talked about as being among the best RTs in the league. That is an impact. Injuries have changed him.

Thereafter, it depends on your standard for impact. However, on this board it is clear that as to equal players, the nonPacker is an impact player and the Packer is JAG.
