So it's fitting that the most intriguing NFL stories are those teams and players that are in a dramatic state of swing.
Indianapolis Colts, for instance. At the end of the Peyton Manning era, they appeared headed for a long rebuilding phase. But rookie quarterback Andrew Luck has been even better than advertised, and Sunday he led the Colts to a 23-20 victory over Miami with a record-setting passing performance.
Chicago collapsed last season without Jay Cutler, losing five of its final six games. Now, not only is Cutler back, but so is the team's havoc-wreaking defense, which forced five turnovers in a 51-20 drubbing of Tennessee that took the Bears' record to 7-1.
And then there's the swingingest of the NFL's swing teams. Arizona won its first four games — the club's best start since 1974 — only to lose its next five, including a 31-17 defeat at Green Bay on Sunday. More bad news for the Cardinals: Their next game is at Atlanta.
"If you look at the five games that we've lost — which is extremely disappointing — the one thing that's consistent is that we've had opportunities to make plays and we haven't done it," Arizona Coach Ken Whisenhunt said. "Green Bay's a good football team. But today, in my opinion, was as much about what we didn't do as what they did do."
The Bears? They charted their own destiny — and did it in vintage defensive style. Cornerback Charles Tillman forced four fumbles, linebacker Brian Urlacher returned an interception 46 yards for a touchdown, and the Bears blocked a punt for another score.
Chicago forced three turnovers in the first 13 minutes, parlaying those into two touchdowns. The 51 points were the most by the Bears since they beat the Packers, 61-7, in 1980.
The Colts (5-3) haven't enjoyed a blowout win this season. All of their victories were by six points or fewer. Still, no one in Indianapolis is complaining. The team has won three in a row, and Luck set a league rookie record by throwing for 433 yards. That broke the mark of 432 set by Carolina's Cam Newton last season.
Luck also became the second rookie quarterback to notch four 300-yard passing games in a season.
The first rookie to accomplish that feat?
Manning, of course.
My favorite Martin
Seattle's Marshawn Lynch ran for 124 yards and a touchdown. Minnesota's Adrian Peterson ran for 182 and two touchdowns. Detroit's Mikel Leshoure ran for three touchdowns.
Exceptional performances, all. But none will be the NFC's offensive player of the week.
That honor will surely go to Tampa Bay rookie Doug Martin, who torched the Raiders for 251 yards in 25 carries with touchdowns of 45, 67, 70 and one yard(s). That came 10 days after Martin gained 214 total yards and scored two touchdowns in a win at Minnesota.
The Buccaneers kept giving Martin the ball at the end of the Oakland game instead of taking a knee to secure the 42-32 victory. The league single-game rushing record was just out of reach, though, and still belongs to Peterson, who in 2007 ran for 296 yards against San Diego in the eighth game of his career.
Martin did walk away with one piece of history. According to NBC, he's the first NFL player to run for three touchdowns of 40 yards or longer.
