Coaching changes are made expressly for purposes of effecting a turnaround, a reversal of failing fortunes. Sometimes they work, most of the time they don’t. The Bears bear (pun intended) witness to that.
George Halas to Jim Dooley? Not so good. Dooley to Abe Gibron? Mmm, nope. Mike Ditka to Dave Wannstedt? Didn’t happen. Wannstedt to Dick Jauron? No better. Lovie Smith to Marc Trestman? Catastrophe. Trestman to John Fox? Some things better, some worse.
Wannstedt had the Bears back in the once-perennial postseason in his year two, where they won a road playoff game; but it was for only one season.
