Logic says no, but it's a subject worthy of consideration in light of the offensive problems the Chiefs have had in the 2011 season. And those difficulties date back to the final two games of the 2010 season in the regular-season finale and then the first-round of the playoffs.
All five of those games were played after it became public that Charlie Weis was leaving the Chiefs as offensive coordinator to take over the same job with the University of Florida. Since that news became known, the Chiefs' offense has tanked.
Up until that game, the Chiefs had been average to slightly above average in offensive production. They were not a great offense in 2010, but the running game worked with Jamaal Charles and Matt Cassel was making good decisions and protecting the football. They owned a 10-5 record and an AFC West division championship with Weis molding the offense each week. There had been ups (503 yards and six touchdowns vs. Seattle) and downs (67 yards and no points at San Diego), but the offense was good enough to be part of a division winner.
But since it became public the week before the final regular-season game that Weis was out, the offense has not been a productive part of the Chiefs. The numbers vividly reveal that the offense has taken steps backward in the last five games that counted:
Has the bottom dropped out of the Chiefs offense because of Weis' departure? The easy answer would be yes, just look at the numbers. There's an obvious drop-off in production and efficiency in the last five games.
Now, it's not like the Chiefs were one of the best offenses in the NFL last year with Weis coordinating the unit. They finished No. 12 in yards thanks to their No. 1 finish in rushing. They were No. 30 in passing yards, finishing ahead of only Arizona and Carolina. Both of those teams have new quarterbacks this season. The Panthers have a new head coach and offensive coordinator. Neither team was anywhere near the playoffs in 2010; both finished last in their divisions.
But the Chiefs were in the playoffs, did finish first in the AFC West, and they have the same head coach and quarterback this year as last. The only thing different coming into the 2011 season was that Weis was gone and Bill Muir was promoted from his spot as offensive line coach to take his place.
Whatever the reason Weis left - whether for personal reasons or the fact he did not like the working situation with Haley and the Chiefs - since that decision became public, the Chiefs' offense has been a major factor in their 0-5 record in the last two games of the '10 season and the first three of the '11 season.
A Charlie cause and effect? Not in the mind of head coach Todd Haley.
"I don't see any correlation in this year and last year," Haley said. "There's just too much time passed to in any way, shape or form tie the two things together."
"Last year is last year," Cassel said. "We're a completely different team. If you want to pick out two games from last year, I understand those were the two (bad) games last year. But you can also say that there are 10 other games that we played really well, so we can also pull off that.
"I think that's the goal for this team is to get into a rhythm and start executing on a higher level. Hopefully you build off that and that's when you start to roll."
SERIES HISTORY: 10th regular season meeting. Chiefs lead series, 5-4. Both franchises were born out of the American Football League. The Chiefs were one of the original eight AFL franchises as the Dallas Texans. The Vikings were part of the initial AFL lineup until ownership was convinced to leave for a spot in the NFL in 1961. The Chiefs won the last game between the teams in 2007, 13-10.
BY THE NUMBERS: 11/45 - Last season the Chiefs lost 11 games from their starters due to injury. This season, they've already lost 45 games due to the knee injuries that ended the season of TE Tony Moeaki (16 missed), SS Eric Berry (15) and RB Jamaal Charles (14).
QUOTE TO NOTE: "The group of guys we have in this building and our coaches and this team is getting closer, not divided. If a team can stick together through the rough times, then they have a chance to do really good things. We're getting our dose of rough times right now." - QB Matt Cassel.
