Cousins might be a tad bit mediocre but he's above-average mediocre and far better starting QB then lets say Case Keenum, Fitzpatrick at the moment in Miami, Sam Darnold, With a great supporting cast, Cousins will win you 9 games, maybe 10 if he's lucky and his team wins a few close ones, but that's it. He's a poor man's Alex Smith who unfortunately wasn't a late bloomer and never had a few good seasons in his late 20s/early 30's.
