Given that the Offensive Line is nearly 1/4 of the team, this is a much more important number than most people realize. Obviously Phil does, which is no doubt part of the reason why he, year after year, leads the prognosticators in accuracy. (Here's a comparison of
accuracy over the last five years).
His number combining returning experience with performance is not doubt an even better indicator than just raw returns. Recalling Ohio's inability to run the ball last year, Ohio was probably low in terms of offensive line performance last year, too, so I suspect Ohio is near the bottom in this important rating even after adjusting for performance..
