Agree 100%.
Especially in recent years, Shades does not play to win, he plays not to lose. There is a difference.
Conservative offense, good defense, don't turn the ball over, let the other team beat themselves. Thing is, that doesn't work in the playoffs when you run up against better teams who don't make mistakes.
Shades is greatly helped by having the Browns and Bengals in his division.
After Cowher's players (and staff) retired or moved on, we see that Shades is awful at developing players and staff. No coaching tree and his hires are all either yes-men or buddies who aren't smart enough about football to challenge him. We'll see how Smith does but so far his best coordinators were the ones he DIDN'T hire, Arians, LeBeau, and Haley.
Player-wise, his best players have been either can't-miss draft picks who were great college players or vets who came from other teams, especially at the DB position which is odd since Shades started out as a DB coach. He can't develop players, either on offense or defense, for ****.
His ego is big enough that he sees no reason to change anything. In his mind his draft picks are great, his game plans are great, his X's and O's are great, we just didn't execute well enough here and there. Like a guy who wears white shoes and leisure suites, he's convinced that someday his style of football will be back.
