Sam Darnold's early struggles with the Seattle Seahawks raise questions about his stability as the starting quarterback, as the Seahawks coach Mike Macdonald brushes off media concerns. Darnold, fresh off a Pro Bowl season with 35 touchdowns with the Vikings, signed a 3-year, $100 million deal with Seattle. However, limited guarantees in his contract and competition with Drew Lock and rookie Jalen Milroe add pressure. Despite mixed practice results, Macdonald staunchly declares Darnold as the starter, emphasizing the unpredictability of quarterback positions in the NFL.
