The key to that last sentence are the words "when healthy." In the last 3 years, Pouncey has only played 12, 14 and 5 games respectively each season. Adam Gase has admitted he will do his best to keep Pouncey fresh, including limiting him in the preseason and even in practice. It remains to be seen if that will be enough.
The Dolphins have Kraig Urbik, Ted Larsen and Anthony Steen on the roster. All can play center. Larsen will battle for one of two guard spots with Jermon Bushrod and Isaac Asiata, and therefore may be out of the picture as far as playing center goes.
As Armando Salguero of the Miami Herald has reported, the Miami Dolphins aren't exactly planning for the worst in terms of their offensive line. Pouncey's prior injury history speaks for itself, and bringing in Mangold on a 1-year deal in the $2 million range could help Miami put their minds at rest should the worst happen.
Mangold, age 33, could surely be relied on for a few games.
Jay Ajayi's success largely depends on the continuity of the offensive line, which was sacrificed last year when Pouncey went down. And Ajayi's stats and success took a hit when that happened. Somehow, the Dolphins stayed afloat despite the struggles in the running game, but with a tough schedule down the stretch next year, a successful running game - especially on the road - would be crucial.
Here's to hoping someone already on the Miami Dolphins steps up, and if not, here is to hoping someone steps in from outside.
