Colts

Can the Colts keep winning in ugly fashion? There’s a lot to be said for the Colts getting back to .500 after their 0-2 start. But their two victories raise as many questions as reasons for optimism. The performance of QB Daniel Jones in each of the past two games has been concerning, to say the least. After committing three turnovers in a win over the Texans, he was responsible for two more Sunday while the offense was often lethargic. The Colts have shown defensive improvement for the second straight week, but neither of the offenses they’ve played has showed much explosiveness. Still, getting back on track gives the Colts a chance to recover from their poor start.

Most surprising performance: Defensive tackle DeForest Buckner continues to dominate despite recently coming back from a very delicate neck surgery. Buckner, at 32, was all over the field on Sunday, pressuring Washington’s quarterbacks, stuffing the run and more. Buckner chasing down quarterback Marcus Mariota on a scramble was especially impressive, as was his consistent batting of passes at the line of scrimmage. — Stephen Holder

Commanders

Can the Commanders recover from all these injuries? As the saying goes, it’s getting late early for the Commanders. They were already playing minus their top four offensive players — tackle Laremy Tunsil, receiver Terry McLaurin, quarterback Jayden Daniels and guard Sam Cosmi — and then they lost backup QB Marcus Mariota. The good news for them? They’re hopeful Daniels can return in Week 5, but they need McLaurin (hamstring) and Cosmi (concussion) and their returns remain uncertain. And the worst part for Washington: After facing the Giants next Sunday, they play at San Francisco and then host the Eagles and Rams. Injuries plus that schedule equals trouble.

What to make of the QB performance: Athan Kaliakmanis, who was filling in for Mariota, has a big arm and plays with poise, but he’s also inexperienced and playing behind a patchwork line. Bad combo. He completed 15 of 33 passes for 186 yards, with a touchdown and an interception. With Mariota injuring the same knee that sidelined him multiple weeks in training camp, the Commanders need to consider signing a veteran to back up Jayden Daniels. However, the line needs to provide more help or it won’t matter. — John Keim

Next game: at Giants (Sunday, 1 p.m. ET)

Fantasy football takeaway: With Mariota (knee) and Daniels (elbow dislocation) both injured, the Commanders’ offense is in a precarious spot. Kaliakmanis had his moments — he was 2-of-6 for 95 yards and a touchdown on deep throws — but he’s a raw prospect. If he has to start in Week 5, downgrade the rest of the Commanders’ skill position players across the board. — Cockcroft
