That is literally made up. Feel free to let me know how you're determining that. It's not even the worst line in the league THIS year, let alone all-time.
what part?....you must be joking to not realize this line has 2 starters that can’t make other NFL rosters....a mediocre guard playing left tackle...a lower level center and a rookie 3rd round pick at left guard(Who was forced to play left tackle last week also....this is as bad as it gets.
And yes...Josh Rosen has gotten a raw deal....Arizona was the worst team in the league last year whose entire starting line was on IR by mid-season...his OC was replaced early in the season by a rookie OC.
And now he gets traded to a team intentionally divesting itself of what talent it has to Tank for Tua.
