The Atlanta Falcons, San Diego Chargers and Baltimore Ravens have the three oldest collections of starters in the NFL. 

The Kansas City Chiefs, Seattle Seahawks and Cincinnati Bengals are the youngest.

Former Vikings head coach Bud Grant had a popular saying that "for every young guy you start, you lose a game."

Pete Carroll worked for Grant early in his coaching career, but has had one of the youngest teams in the NFL during his tenure with the Seahawks.

"I was of that mindset in classic fashion until I had to be in charge of calling all the shots and then it just flipped in me that we don't know where we're going unless we find these guys out," Carroll said. "One of the really exciting things about playing guys early is ... by the middle and to the end of the season, you’ve developed players that fit into your rotations now that add to your depth and also add to the opportunity to not over-play your older guys." 

Below is a full list with the rank in offense/defense in parenthesis.

The Lions are thin in the backfield with just 12 days before the season begins.

Detroit GM Martin Mayhew has been calling around looking for help at running back.

Kevin Smith is No. 1 on Detroit's depth chart, but he injured his ankle this weekend against Oakland. Jahvid Best will begin the season on the PUP list and Mike Leshoure has been suspended for the first two games of the season for violating the NFL's substance abuse policy.

The Redskins have traded cornerback Kevin Barnes to the Lions.

Washington had informed Barnes earlier in the day that he would be released, but the team later found a trade for him.

Barnes was a third round pick in 2009 and was mainly a nickelback last season.

Matthew Stafford broke a blood vessel in his left hand, but still expects to be ready for his team's regular season opener against the Rams.

Stafford suffered the injury against the Raiders on Saturday.

"It was just scary to look down and see your hand swelling up by the second," Stafford said. "That kind of freaked me out. The skin kind of just grew by the second. I didn't know what was going on."

The NFL has 12 starting quarterbacks who are 24 years old or young.

Six of those 12 played high school football in the state of Texas.

Andrew Luck, Robert Griffin III, Andy Dalton, Ryan Tannehill, Christian Ponder and Matthew Stafford all played in Texas.

Matthew Stafford hurt his left (non-throwing) hand in Saturday night's preseason game against the Raiders.

The Lions quarterback was hit in the hand by a helmet in the second quarter.

"It was just scary to look down and see your hand swelling up by the second," Stafford said. "That kind of freaked me out. The skin kind of just grew by the second. I didn't know what was going on."

X-rays were negative and Stafford is expected to be fine by the team's Sept. 9 opener.

The Bears have the best uniforms in the NFL, according to Paul Lukas of Uni Watch.

"True, the helmet design is starting to look a tad dated," writes Lukas. "But the striped sleeves, striped socks (now a rarity in the NFL, alas), unique number font, and even the perma-memorial to Papa Bear all score major points, and the Bears may be the only team in the league who look as sharp on the road as they do at home. The cream of the NFL crop."

The Packers, Steelers, Raiders and Eagles round out the top-five.

"Just suit up, baby," writes Lukas about the Raiders. "Silver and black look just as good today as they did when Al Davis came up with them. There's probably some marketer out there who wants the team to dress up like the fans in the Black Hole (and hey, that actually could be fun as a one-off thing), but you don't mess with something this elemental. Also: The Raiders are among the few NFL teams that wisely have declined to adopt the new Nike collar format."

The Lions may start Jahvid Best on the physically unable to perform list to begin the 2012 season.

Best continues to recover from a concussion he sustained last season, the third of his career.

"Particularly with concussions, time is always beneficial," Jim Schwartz said. "You've seen that with a lot of other guys that have come back. That would buy us time if we had to cross that hurdle."

The Lions were optimistic about Nick Fairley coming into training camp healthy for the first time in his NFL career.

But Fairley has three tackles and one personal foul penalty during the first two preseason games.

Fairley has also been unable to get his conditioning to a point where he is able to stay on the field for moe than a few plays at a time.

"(Fairley has) all the tools to be a very good player," said defensive coordinator Gunther Cunningham. "(He needs to) grow up fast and be consistent."
