Bears, Raiders among non-playoff teams that have made biggest leap since 2024 NFL season

The Chicago Bears significantly improved their biggest weaknesses by overhauling both the coaching staff and the offensive line. Hiring offensive coordinator Ben Johnson is expected to unlock a dynamic offense. General Manager Ryan Poles invested heavily in proven veteran offensive linemen, transforming the unit from a liability to a potential asset if healthy. This sets up quarterback Caleb Williams for success, and the Bears need him to make a significant leap in his second year to capitalize on the positive offseason changes. Additionally, the draft added tight end Colston Loveland and wide receiver Luther Burden III as offensive weapons. These improvements in coaching and roster talent should help Chicago compete for a playoff spot.

The New England Patriots enhanced their team across multiple levels this offseason. They hired proven head coach Mike Vrabel and went on a free agency spending spree, acquiring defensive lineman Milton Williams, cornerback Carlton Davis, outside linebacker Harold Landry, and wide receivers Stefon Diggs and Mack Hollins. The draft yielded two immediate starters in first-round pick Will Campbell and second-rounder TreVeyon Henderson, both expected to aid quarterback Drake Maye's development in his second year. These moves position Vrabel's team to potentially finish second in the AFC East and return to the playoffs.

The San Francisco 49ers focused on recovering from an injury-plagued and disappointing season marked by defections, distractions, and poor run defense. They spent the offseason rebuilding morale, which included retaining key players and welcoming back a beloved leader. The defensive front was fortified. Crucially, the team benefited from a full offseason to get healthy, expecting stars like Christian McCaffrey, Trent Williams, Ricky Pearsall, Brock Purdy, and Nick Bosa to be at full strength for the season. Wide receiver Brandon Aiyuk is also anticipated to return from injury later, providing a boost. With good fortune and a favorable schedule, the 49ers have the potential to dramatically increase their win total.
