Dave Wannstedt was a terrible coach. He understood the value of rushing the football? Yes. Still a terrible coach. To my dying day I will never forget Wannstedt telling a sideline reporter, at halftime with the Dolphins up by 10, that the team's plan in the 2nd half was to 'keep it close and try to win it in the 4th quarter.'
As for Harbaugh, our problem is not that we might get Jim Harbaugh in exchange for a couple of draft picks. Our problem is that we probably won't get Jim Harbaugh, even if we offer up the picks.
Of the three guys I mentioned, I know Kubiak will be available. You want to fix the offense? You want a guy who will run the ball and actually run plays a QB currently on the roster is best suited for? That's who you can go get. Of course, we'll wind up hiring Adam Gase, or something, because he's been Peyton Manning's coffee run guy for the last 2 years.
