It was not good when both Evan Mathis and Mike Iupati got hurt in the same game, something that could have crippled the Cardinals' offensive line. But perhaps it turned out to be the best thing that could have happened.
Earl Watford slid in to Mathis' spot -- the spot that, in theory, Watford was drafted to play back in 2013, bookending with hopeful future left guard Jonathan Cooper. John Wetzel, a tackle by trade, filled in nicely for a game-and-a-half for the hobbled Iupati. All the Cardinals did in those two games was dominate in the running game.
Bruce Arians gave the entire offensive line (and running back David Johnson) game balls for the 171 rushing yards against the Jets.
Iupati should be back this week, sending Wetzel back to the bench. But if there is another injury at some point, the Cardinals have to be much more comfortable if Wetzel has to come in and play guard. Thinking long-term, however, the Cards may have some options beyond 2016. Iupati will still be around, but Mathis' career is likely over, his one season in Arizona never really getting going because of multiple injuries. Watford is going to be an unrestricted free agent. Maybe he is brought back, the man to replace Mathis in 2017. If not, perhaps Wetzel is a candidate to fill in on the line, another big lineman who has really come out of nowhere to be a viable possibility.
