Still not quite right. In 1986, Jimmy was the starter. I believe Fuller was second string and Tomczak was third (could be the other way around wih those two). Jimmy was injured in the opener and struggled to stay in the line up for the rest of his year. And if I'm not mistaken, Steve also ended up injured. Regardless, Tomczak ended up getting significant playing time (Mike finished the season with more passing yards than Jimmy, and the Bears credit Mike with 7 wins and no losses. Jimmy is credited with 6 wins and no losses, leaving Fuller no wins and two lossses.
Bears QB Starting Records Take a peek at page 2).
After game 12, Jimmy was put on IR (after getting pile drived into the turf during the game), Fuller was still nagged by injury, leaving just Mike as his only healthy QB. So Ditka traded for Flutie.
Yes, Mike was unspectacular as the starter, but given the Bears strong defense, he was 7-0 as the starter (Hmm. Strong D, Weak O, but winning record. Sound familiar?). 7-0 sounds like a good reason to start the playoff game. Looks like Tomczak got screwed out of starting in the playoffs, because Flutie had a good game in the meaningless last game of the year. Ditka's "hunch" was DF would spark the Offense. (That also sounds familiar).
Funny, some people want to believe DF got shafted by the Bills, but somehow, these same people will attempt to lead you to believe DF earned his chance to start in Chicago.
