Who Should I Start? Justin Fields or J.J. McCarthy

Sunday, June 28, 5:37 AM

When the Kansas City Chiefs sent a sixth-round pick to acquire veteran quarterback Justin Fields from the New York Jets, it opened a brief sell window for dynasty managers who have held the disappointing former first-round pick through his latest stints with the Jets and Steelers. Chiefs starting quarterback Patrick Mahomes tore his ACL in Week 15 of the 2025 season, and at the time of the trade, his availability to begin the year was in doubt, putting Fields in line to make a Week 1 start for his fourth team in as many seasons. Since then, optimism about Mahomes' recovery has led many to believe that the two-time MVP will be ready to start the year, and he and the Chiefs recently agreed to a reworked contract that added two years to his existing deal, making him the NFL's first half-billion-dollar man. While the chance of reinjury and Fields' own fantasy-friendly play style still keep the former Bear, Steeler, and Jet among the most valuable backup quarterbacks in superflex dynasty leagues, his overall value continues to dwindle year after year, and Fields is now RotoBaller's QB41.
