To say that Philly doesn't have quality interior OL, ergo we can get by without Martin, is silliness. One, because Martin clearly makes the other two alongside him better. Biadasz and Steele aren't nearly as good when having some random guy between them. Conversely, while Dickerson is a very good interior OL, he also has the best C in football on one side and one of the better young LTs on the otherside. Philly doesn't "need" to have a really good OG there. Nevertheless they do.
We on the otherhand absolutely need a high level OG because of the way our OL is built. If Martin, for whatever reason, doesn't play in 2023, this team isn't contending for a SB. His not being there has a massive trickle down to where now you don't have a RG problem, you have a right side of the OL problem. And then if Tyron goes down, which he has for a few seasons, suddenly the entire OL is screwed. Tyler Smith can't fix it all.
