That decision is a long way off, and it is a part of a series of determinations Jets officials will have to make about their quarterbacks. The organization loves McCown, who offered steadiness and surprisingly strong play last season and who is viewed as the ideal mentor for Darnold. Bridgewater, who appears to be moving well as he continues his recovery from a devastating knee injury he suffered two years ago, could be attractive to other teams if he performs well in the preseason, although the Jets could choose to keep all three signal-callers in what appears to be a convivial and cohesive quarterback room. Complicating the decision about the starter, the Jets play their first three games in the first 11 days of the regular season, with their fourth at the Jacksonville Jaguars, who boast one of the best defenses in the league. That would be a gauntlet for Darnold.
