The NFL offseason is always full of tough decisions that have significant consequences. Teams must navigate the trade and free-agent markets and the draft, and the moves they make—or don't make—have a lasting impact.

Sometimes, a team gets the biggest payoff from a move it doesn't make. 

According to NFL Network's Ian Rapoport, the Tampa Bay Buccaneers initially planned to bring back quarterback Jameis Winston last offseason. They instead decided to move on, gambled on Tom Brady and finished the season with a championship.

While not every team has the potential to make a championship run in 2021, each has at least one move to avoid this offseason. Whether that involves letting a key player walk, overpaying in a trade or free agency, or overvaluing a draft prospect will depend on where the franchise sits between rebuilding and ring-chasing.

Here, you'll find one move that each franchise should avoid this offseason, based on factors like cap space, player potential, past production and roster construction. 

Arizona Cardinals: Overpay to Keep Patrick Peterson

Cornerback Patrick Peterson has been a defensive mainstay for the Arizona Cardinals for a decade, but he could depart in free agency this offseason. While the Cardinals might love to have him back for another season or three, they can't afford to overpay to keep him.

While Peterson is still a starting-caliber cornerback, he isn't the elite shutdown defender he once was. He allowed an opposing quarterback rating of 98.2 this past season and 99.0 in 2019.

The Cardinals are projected to have more than $19 million in available cap space, but they shouldn't throw gobs of money at a 30-year-old defender who's past his prime. Paying top-market price for Peterson would only make sense for a team that views itself as a piece or two away from a championship.

While the Cardinals do appear to be on the rise—they narrowly missed the postseason in 2020—they aren't likely to be a title contender within the next year or two.

Atlanta Falcons: Trade Matt Ryan

Will the Atlanta Falcons move on from quarterback Matt Ryan this offseason? It's possible.

The Falcons could consider taking a quarterback with the fourth overall pick in the draft, and team president Rich McKay has left the door open for the front office to move both Ryan and wideout Julio Jones.

"Give us a plan," McKay said, per Jeff Schultz and Tori McElhaney of The Athletic. "Show us what you want to do and show us why. Show us how this gets us to Ws and make sure you execute the plan."

While the presence of wideout Calvin Ridley would make a Jones trade more palatable, Atlanta must keep Ryan on its roster for another year. Even if the Falcons draft a quarterback of the future at No. 4, there's no guarantee he'll be ready to start as a rookie.

Moving on from Ryan would also be financially problematic, as he has nearly $50 million in dead money remaining on his contract. The Falcons need to hang onto Ryan at least until the 2022 offseason, when his dead-cap hit will drop to just over $26.5 million.

Baltimore Ravens: Overpay to Keep Matt Judon

Last offseason, the Baltimore Ravens used the franchise tag on edge-rusher Matt Judon. They didn't sign him to a long-term deal, though, which means he's again slated to hit the free-agent market.

The Ravens should want to keep Judon, who had six sacks and 32 quarterback pressures in 2020, but they shouldn't pay top-market value to do so. The 28-year-old could easily cost $15 million per year considering he earned $16.8 million on the tag last season.

The Ravens are projected to have more than $28 million in cap space, but they can't afford to spend over half of it on a defender who has never produced a double-digit-sack season. Baltimore has other key contributors headed to free agency, including center Matt Skura, running back Gus Edwards (restricted) and edge-rusher Yannick Ngakoue.

The Ravens also need to find a legitimate No. 1 receiver and extend quarterback Lamar Jackson at some point in the near future. Judon should only be back on a deal that provides Baltimore with financial flexibility.
