There's not much the New England Patriots have to regret over the last decade-plus. They are the NFL's most successful franchise in that time.

Even if there is a legitimate second guess or two, well, they'd hardly admit to one. Playing the Minnesota Vikings on Sunday, though, at least provides a scenario to ponder.

No, the Patriots didn't make a mistake by trading backup quarterback Matt Cassel, who will start on Sunday for the Vikings against good friend and former mentor Tom Brady for the first time. Brady has fared just fine since Cassel was dealt to Kansas City in 2009.

The player the Patriots, and a lot of teams in the league for that matter, could use is Cordarrelle Patterson. During last year's draft, the Patriots accepted four low picks to give up their first-round pick to the Vikings, who were enamored of the skills of the wide receiver and kickoff returner.

"We made the decision based on what we felt was best for our team," Patriots coach Bill Belichick said this week.

Patriots wide receivers remain a developing group without a true star, still trying to establish the kind of dynamically versatile player the Vikings are grooming Patterson into. He turned a toss sweep into a 67-yard touchdown last week in the opener at St. Louis, a 34-6 victory, and has scored in six straight games.

Patterson said this week he uses the Patriots' decision to pass on him as a little extra motivation.

"It's always good to have that chip on your shoulder, just to go out there and just try to execute (against) the teams that didn't even pick you when they said they wanted you," Patterson said.

The Patriots lost to the Miami Dolphins 33-20 last week, and have not started a season 0-2 since 2001.

"We're a long ways from the team we're going to be," Brady said. "We hate losing ... it's a terrible feeling around here. It's a quality of life issue we all face when we lose, and hopefully it motivates us to go out there and ... try to beat a very good team."

Two other division favorites, the Green Bay Packers and Indianapolis Colts, also go into Week 2 off losses, but also are far from panicking.

The Packers have had plenty of time to prepare for the New York Jets, but also lots of time — since Sept. 4 — to stew about how poorly they performed at Seattle. Now, they get an opponent whose defense can play tricks on anyone.

Green Bay faces another tough running game led by Chris Ivory and Chris Johnson after yielding 207 yards on the ground to the Seahawks.

A shootout is expected in Indianapolis on Monday when the Colts host the Philadelphia Eagles.

The Eagles' fast-paced offense overcame early injuries on the offensive line to rally from 17-0 down to beat Jacksonville 34-17. LeSean McCoy and Darren Sproles combined for 145 yards rushing, and face a Colts defense that has traditionally struggled to stop the run.

The Colts' best trait is their resilience. They don't worry when they get behind, don't flinch at the sight of turnovers, and don't look back when injuries hit. Denver led them 24-0 last week but Andrew Luck got Indianapolis within a touchdown of forcing overtime and into position for a potential tying score in the closing minutes before the drive stalled.

"I saw the stat, (Luck) has the most fourth-quarter comebacks in the first two years in the league of any quarterback," Eagles coach Chip Kelly said. "There's a confidence in that team. Chuck's (Pagano) done such a good job of providing and creating an environment for those guys that they feel like they're in every game."

Also on Sunday, it's Chicago at San Francisco, Seattle at San Diego, Detroit at Carolina, Kansas City at Denver, New Orleans at Cleveland, Atlanta at Cincinnati, Miami at Buffalo, Dallas at Tennessee, Arizona at the New York Giants, Jacksonville at Washington, St. Louis at Tampa Bay, and Houston at Oakland.

The week's action began in Baltimore, where the Ravens pushed aside the turmoil of Ray Rice being released — and suspended indefinitely by the team — with a 26-6 rout of the archrival Pittsburgh Steelers.
