Questions can be just as informative as answers.At this time last year, for example, we wondered whether J.J. McCarthy offered a high enough floor for the Vikings (uhh), who would protect Justin Herbert (no one) and whether the Rams had enough talent at cornerback (not then).This year’s questions could prove as consequential. Before I dig into the four most concerning, a quick look at all 32 raised by The Athletic’s writers. See if you can guess which I consider the most worrying.I’m not worried about a team’s depth at any given position, like the Vikings’ edge rushers or the Steelers’ or Jets’ backup quarterbacks. We can’t predict which backups will need to step up months from now.But I am alarmed about these four situations, listed in order of severity (excluding the Browns, whose quarterback situation is perpetually severe):1. Did C.J. Stroud get enough help? Despite making the postseason in each of his first three seasons, the Texans are hesitant to sign their 25-year-old quarterback to a long-term deal. Blame his playoff collapse, which helped convince Houston to again overhaul its offensive line and running back rooms. With his fifth-year option exercised, time is running out for both him and the team to decide on his future.2. How soon can Dolphins rookies contribute? Quickly, the new regime must be hoping, as coach Jeff Hafley and GM Jon-Eric Sullivan inherited the league’s bleakest roster. After a league-high six draft picks in the top 100, Miami was No. 9 in Dane Brugler’s post-draft rankings. The team hopes to end 2026 like last year’s Browns: with some new building blocks.3. Did Jayden Daniels get needed support? The honeymoon is over in DC. The miracle NFC championship appearance to begin the Daniels-and-Dan Quinn era was followed by a sophomore slump. Daniels was hurt, and the Commanders went 5-12. The coach’s job is safe for now, but new coordinators on both offense and defense hint at urgency. Daniels still deserves better weapons, and I’m not sure Brandon Aiyuk would be the answer.4. Cardinals defense any better? Short answer: unlikely. Despite ending the season with an 0-9 stretch that included allowing 35.2 points per game, Arizona spent its offseason investing in offense. This is the league’s worst team on paper, though at least it has … a fun running back?!
