Nobody ever adds the qualifiers of the team mates they played with to Joe Montana though he enjoyed several legendary players on his team too.
Same thing with Emmitt.
Same thing with Irvin.
"The team around them" attempt to discredit has been applied to them all. At some point, someone has to be responsible for all those plays that got made. Yeah, the offensive line was awesome, but so were the 49ers. Even with those lines the skill players still had to be special to consistently make big plays to score the points that took advantage of the protections of the line.
Aikman at his best is top 10 all time that I've seen play. So is Irvin, and Emmitt is the GOAT.
