The success of the 2018 Arizona Cardinals may come down not to their quarterback(s) necessarily, but the play of the offensive line. If those five players can show a significant improvement over the five of last season, suddenly the rest of the Cardinals will start to look pretty good — or at least we’ll be reminded that the rest of the Cardinals, in many cases, have already been very good for years.
It’ll just be a real struggle for Arizona’s offensive line to both make that leap and stay on the field for the whole season.
