The 2022 NFL offseason has seen an arms race unlike any other, as teams have been more aggressive than usual in beefing up. We've seen trades for Russell Wilson, Matt Ryan, Carson Wentz and Deshaun Watson, and that's just the major quarterback acquisitions. 

J.C. Jackson, Khalil Mack, A.J. Brown, Tyreek Hill and Davante Adams all switched jerseys too. 

Yet pressure remains to maximize rosters as the season creeps closer, and some high-quality free agents are still waiting to find a home.

Here's a look at the top Super Bowl favorites based on the latest odds from Draftkings Sportsbook and a free agent who could help each.

Buffalo Bills: G/T Daryl Williams

Super Bowl Odds: +600

It's no surprise that the Buffalo Bills are the Super Bowl favorites, as they have the league's most complete roster. 

Their biggest concern is depth. They have it in a lot of spots, but the interior of the offensive line is one area where it could be better. 

Rodger Saffold (left) and Ryan Bates (right) project to be the starters at guard. Per Pro Football Focus, Saffold was ranked 31st among eligible guards last year. Bates is more of a project. He made four starts last season and earned a respectable 64.3 grade from PFF while giving up no sacks. 

If either of them gets hurt or Bates fails to grow into his role, the options are bleak. Cody Ford couldn't hold down a starting job last season, and Ike Boettger was a liability in 10 starts. 

The team has not re-signed Daryl Williams, but it's worth considering. The 29-year-old has been in Buffalo for the last two seasons, knows the offense and can play both guard and tackle. That could prove incredibly useful as the Bills go after their first Lombardi Trophy. 

Tampa Bay Buccaneers: LB A.J. Johnson

Super Bowl Odds: +700

The Tampa Bay Buccaneers have one of the league's best linebacker tandems in Devin White and Lavonte David. After that, the positional picture gets murky. 

Kevin Minter saw the most work as a backup off-ball linebacker for the team with 29 percent of the defensive snaps. He remains unsigned, though. 

The fact that A.J. Johnson is still a free agent is a bit of a surprise.

It's obviously a concern that the linebacker missed all but six games in 2021 with a torn pectoral muscle, but Josey Jewell suffered the same setback and the Broncos still handed him a two-year $11 million contract in March.

Johnson is 30 years old, but he's only been in the league for four years. When he's been healthy, he's been a solid starter, especially against the run. Per PFF, he had two seasons with a run defense grade of 90.0 or higher in Denver. 

A season in a part-time role with a Super Bowl contender such as Tampa could make him a sought-after starter in 2023 free agency. 

Kansas City Chiefs: Edge Melvin Ingram

Super Bowl Odds: +1000

No reason to get complicated here. The Kansas City Chiefs acquired Melvin Ingram for the back end of the 2021 season, and he played an important role, including getting two sacks and three quarterback hits in the playoffs. 

The Chiefs have not brought him back but did place the rare unrestricted free-agent tender on the pass-rusher, per Field Yates of ESPN. The tender is a one-year contract worth $4.4 million and demonstrates at least some interest retaining him.
