The continuing saying that Cooper, Matthew and Aaron are/were the load bearing walls may not be all together true....Look at last year if the 3 are considered the walls we actually had 2 walls and a planter wall....Cooper was not a constant last year. Now when we looked worse was the packer game, that's the game we played without Matthew. I think the other 2 walls played. As big as Aaron is, as dominating as he is, Without Matthew or his equal we have no ring.
I think we have a 4th wall that was never mentioned and that's Sean.....that 4th wall is what keeps the building standing. Aaron may or may not come back, if he comes back when it looks like the RAMS are on the cusp of getting another ring, well, that means they got there without him.....he'd be a great addition because he'd be fresh and that would be VERY dangerous for other teams, but if we get there without him it also means the entire team took up slack for him being gone.....
To me that would be much more huge/important a factor over him coming back for say 2 games to get another ring.
