There was one specific problem that doomed Dick Jauron with the Buffalo Bills.
It wasn't installing the no-huddle offense. It wasn't signing Terrell Owens. It wasn't firing the offensive coordinator 10 days before the regular-season opener. It wasn't Leodis McKelvin's fumble or Roscoe Parrish's bobble.
What sunk Jauron and led to his dismissal Tuesday can be directly attributed to the Bills' organizational approach at offensive tackle. Jauron certainly had a voice in how they handled it, but vice president of pro personnel John Guy had input and chief operating officer Russ Brandon signed off on it.
The movie is based on the book by Michael Lewis, author of "Moneyball." Oher was the central character in Lewis' book, but the real subject of "The Blind Side: Evolution of a Game" was about how left tackle had evolved into the second most important position in football.
The problem in Buffalo is that they don't have a tackle. Or they've had too many. Either way, it has been a disaster.
What follows is a timeline of how the Bills went from having a respectable pair of tackles to the most abominable group in the NFL.
April 25 and 26: Bills decline to select a tackle in the 2009 draft.
April 26: I asked Jauron what the Bills intend to do at tackle.
"We went into the draft having discussed that after the trade of Jason, saying 'Do we feel like we have to have a tackle?' And I think we all agreed ... we're not going to stray far from our grades just to take a tackle," Jauron said.
"We felt like we have guys that can play there. So there's no sense in passing up a guy we think is significantly better at another position just to feel like we've plugged a number in. We weren't going to do that."
May 14: Scouts Inc. analyst Matt Williamson observes "Buffalo might have the worst offensive tackles in the NFL."
Aug. 28: A team source tells me Demetrius Bell, despite a back injury, has overtaken Walker as the Bills' left tackle of choice. Bell is entering his second year and hasn't played in an NFL game.
Sept. 5: Bills cut tackle Kirk Chambers, who started four games in 2008.
Sept. 8: Bills cut Walker, re-sign Chambers. Jauron is asked if he overestimated Walker's ability.
"Probably," Jauron replies. "We clearly felt we could move him in, and he'd do the job. He just wasn't playing up to our expectations. So we felt like it was time to make that move."
Sept. 14: Bills start the season with Bell at left tackle and Butler at right tackle. Their entire opening-night offensive line has 47 career starts among them.
Sept. 20: Butler suffers a season-ending knee injury against the Tampa Bay Buccaneers.
Oct. 4: Chambers, inactive the two previous games, starts at right tackle against the Miami Dolphins and gives up 2.5 sacks to first-year outside linebacker Cameron Wake. ... Scott starts at left tackle for Bell.
Oct. 18: Meredith makes his first NFL start at right tackle against the New York Jets.
Nov. 1: Meredith suffers a knee injury against the Houston Texans.
Nov. 16: Through Week 10, Bell is the NFL's most penalized player regardless of position.
Nov. 17: Bills fire Jauron, name defensive coordinator Perry Fewell interim head coach.
