The durability part is noted and agreed on.
But how has Roethlisberger capitalized on anything? Two playoff appearances? An embarrassing AFCGG loss to the Pats where was, as usual, slow out of the gate and then on fire during garbage time? That same Sunday, Rodgers Packers lost to the Packers. If you consider staying on the field and leading a playoff supporting cast to the postseason in 2017 (while an injured Rodgers did not make the playoffs), that seems like a pretty weak case.
The Steelers have had a loaded offensive line and immense talent for years now. Roethlisberger has just reinforced my suspicion that he cannot carry a team without a super elite defense like the Polamalu units. He’s inconsistent, has wildly bad road splits, and can’t get along with anyone. Emmanuel Sanders and numerous other players criticized him for his lack of leadership. He whined on his radio show and threw Antonio Brown under the bus, causing the drama that resulted in Brown leaving. He’s a worse leader and on-field player than Rodgers, and his supporting casts have been superior to Rodgers. A couple of Rodgers injuries isn’t close to enough to balance the scales.
