"He could play today. He's in the best shape I've ever seen him in, physically."
Those are the words of agent Bus Cook in regards to—who else?—Brett Favre.
While the article in The Birmingham News that quoted Cook wrote "he's merely making an observation," after watching some of the lackluster quarterback play through three weeks in the 2013 NFL season, it's hard to think that Favre would be worse than every signal-caller in the league today.
Let's take a look at which teams could take a look at Brett Favre in a buy-or-sell format.
The Jacksonville Jaguars currently have the worst quarterback situation in the NFL.
Blaine Gabbert was the worst starting signal-caller when he was healthy, and Chad Henne has proven to be less effective during his time under center for Gus Bradley's team, as evidenced by the atrocious offensive start to the 2013 campaign.
The collection of skill-position talent in Jacksonville is relatively sub-par, but a new head coach and general manager can't rebuild a team in one season.
While Brett Favre would be a tremendous upgrade for the Jaguars at the game's most important position, signing a soon-to-be 44-year-old quarterback doesn't align with a franchise at the beginning stages of an overhaul that's likely looking at a Top 5 draft selection in 2014.
Dennis Allen is three years younger than Brett Favre and is in his second season as the Oakland Raiders head coach.
Are Allen and second-year GM Reggie McKenzie slowly but surely entering desperation mode?
If they feel their jobs are on the line this season, signing Brett Favre could be of interest to them, especially if Pryor's concussion is significant.
The Cleveland Browns stunned everyone by trading Trent Richardson to the Indianapolis Colts for a 2014 first-round pick.
The move showed that, more than anything else, head coach Rob Chudzinski, GM Michael Lombardi and CEO Joe Banner are looking ahead to the future of the organization they're running.
Brian Hoyer was good enough against the Minnesota Vikings to lead Cleveland to victory in Week 4, and Lombardi is a huge advocate of Hoyer as the starter.
According to NFL.com's Chris Wesseling, Lombardi said the following about Hoyer in 2011: "I think Hoyer has all the traits you need, in terms of leadership, toughness, arm strength, ability to move the team."
If Hoyer continues to play well, the Browns may move forward with him as the No. 1 quarterback. If not, the Browns have positioned themselves to draft the signal-caller of their choice next May.
Although Brett Favre could fit well with Chudzinski's vertical passing offense, the organization is simply going in a totally different direction.
The Tennessee Titans have done everything in their power to create and atmosphere conducive to success for Jake Locker.
Speedy wideout Kendall Wright was drafted in the first round in 2012. Tight end Delanie Walker was added in free agency, as was offensive guard Andy Levitre. In Round 1 of the 2013 draft, offensive guard Chance Warmack was selected.
Now Locker has no excuses.
Through three games this season, his completion percentage is up near 60 percent, has yet to throw an interception and the Titans are 2-1.
Things are looking up.
Mike Munchak is in his third year as Tennessee's head coach and has yet to lead his team to the playoffs.
If Locker regresses, Brett Favre could be a legitimate option. Right now, it looks as though Locker is improving.
Christian Ponder needs to get better and get better fast to hang onto his job in Minnesota with the Vikings.
He's shown minimal improvement during his stint as the starter for Leslie Frazier, and his completion percentage is under 60 thus far in 2013 with two touchdowns and five interceptions.
His team went 10-6 and went to the playoffs in 2012, but many believed Ponder held the team back.
Frazier probably isn't on the hot seat, but things will get more stressful for him if his signal-caller continues to struggle on a weekly basis.
The Vikings already experimented with Brett Favre, but actually, they're in a situation in which the elder quarterback could help sustain the team's viability in 2013.
ESPN's Adam Schefter reported that Tampa Bay Buccaneers head coach Greg Schiano has decided to bench Josh Freeman for Mike Glennon.
If Glennon flourishes, Schiano will probably hang onto his job.
If not, Schiano will likely be shown the door, and realistically, a new GM would be in place in January.
The Buccaneers head coach runs a tight ship, and he'll have to live with this decision for the remainder of the season.
If Tampa Bay continues to lose, Brett Favre wouldn't help the immediate or long-term future of the franchise.
It's a bit early to shut the door on Carson Palmer as the Arizona Cardinals quarterback.
Through three games, he's completing just shy of 58 percent of his passes with three touchdowns and four interceptions in Bruce Arians offense.
The NFC West may not be as strong as many thought before the season, and the Cardinals defense should keep them competitive, although the injury bug has hit the linebacking unit pretty hard.
If Palmer eventually seems to be the reason why the Cardinals are losing, but they remain in the playoff hunt, Arizona could look to Favre for a quick fix.
But it's Arians' first year on the job—if he holds a high draft pick in 2014, he'd likely draft a quarterback to fit his offense.
