ESPN article on Arians decision:
http://espn.go.com/nfl/story/_/id/7489906/pittsburgh-steelers-chose-not-keep-bruce-arians-bucking-ben-roethlisberger-sources-sayThis seems odd: Not so much the "retirement," or the fact that Ben didn't like it, but this quote:
The sources said the move was made in order to shift the offense back toward its blue-collar identity of years past, in line with the desires of Steelers president Art Rooney II.
This would be a problem for me if I'm Tomlin. As far as I know, Rooneys have never been that hands on with the on-field decisionmaking. Maybe they have and kept it under wraps, but dunno. If true, this is the right move for the wrong reason. Today's NFL is more and more about the short passing game. The plan for the next 5 years should be to continue putting the ball in Ben's hands, but dictate that he gets rid of it faster. I don't think the 60-40 run/pass ratio is a positive direction.
