The Titans fans need to be patient. Whiz started 3-5 in AZ then went 28-18 including 4 playoff wins and an NFC Title.
Whiz took the Tiaptans job knowing he had no savior like Warner hanging around, but when the Chargers HC wants toy to move on by trying to sell you as a Hc for next season, you have to move on or they fire you.
BTW, Whiz said no to Detroit because the Lions put lots of restraints on him and he could be only the HC there and no other power such as personnel, etc. This all meanstthey really did not want him.
