Cardinals’ biggest mistake at 2026 NFL Trade Deadline

The Arizona Cardinals' failure to trade Marvin Harrison Jr. and Jacoby Brissett at the 2026 NFL Trade Deadline has been identified as their biggest mistake so far. General manager Monti Ossenfort had previously signaled his willingness to sacrifice established talent for future draft capital, as demonstrated by the trades of Harrison and Brissett.

However, when the deadline arrived, the Cardinals suddenly became reluctant to part with two of their most valuable veterans. This left Arizona with a missed opportunity to accelerate their rebuild. Facing a 3-6 record and at the bottom of the NFC West, Arizona's 2026 season has struggled under first-year head coach Mike LaFleur.

The team's defense has been particularly vulnerable, surrendering 28.3 points per game, while injuries have plagued the offense. Quarterback Gardner Minshew II is among several players who have been sidelined with injuries. While holding onto veterans like Baker and Sweat may provide leadership and stability, the Cardinals failed to capitalize on the opportunity to acquire draft picks that could help build a younger, deeper roster.

Trading Baker, in particular, is seen as a missed opportunity, as he remains a valuable player and franchise icon. The team should have explored the market seriously, even if the return wouldn't meet their expectations. The Cardinals are already dealing with significant injuries and uncertainty at quarterback, with Carson Beck taking over as the starting quarterback.

Additional premium selections would provide more flexibility to address the team's weaknesses. Overall, the Cardinals' hesitation to trade Baker and Sweat could be considered their biggest mistake of the 2026 season.
