Cousins actually comps stat wise with Tarvaris. Slightly more TDs per game, slightly more mistakes. Similar completion percentage early in the career.
When I watch Cousins, I see a guy trying his ass off to win the starting job. He has an advantage on some QBs in that he isn't a spot thrower, but he lacks accuracy when guys are going away from him on a slant. He can hit movers down the seams, but his mistakes are also down the seams, where he stares at receivers.
Gruden and Shanahan before him both do and did him, and RGknee as well, a gross injustice every time they hang the outcome of games on their shoulders. With Morris and Helu, there is no reason to abandon what should be the staple of the team with Morris. In Knee's first year, Shanahan did well with it, but since, both staffs have botched building a safe haven for their young QBs. WE may have resented the handcuffs that were put on Wilson when he first was in Seattle, but we are seeing the dividends of the nest that was built around him now.
