 Of all qualifying quarterbacks last year, Tua graded out number seven, according to Pro Football Focus. You took a look at this offensive line. You got Armstead, and you got Jackson on the tackles. Jackson graded out about middle of the pack. Tron Armstead, as you would imagine, is one of the top. But then you do bring in Brewer to play center, who is the 11th graded center out of 36 centers that were qualified to be graded over there.
