Dart said.Dart also said this play helped him develop a mentality of always being prepared, even if he's on the sidelines."I was like, all right, I didn't know that I was going to go in for one play and then come back out," Dart said as per ESPN. "So I think that's just (that) he's making up scenarios where you never know when your number's going to be called, and you got to be ready for that."He's done it in practices. So I think that that kind of taught me that I need to continue to warm up on the sideline. You just never know when things like that are going to happen."Jaxson Dart completed 14 of 16 passes for 137 yards and one TD. He also had a rushing TD in the third quarter.Will Jaxson Dart replace Russell Wilson as Giants QB1 in 2025?The Giants brought in veteran quarterback Russell Wilson this offseason, and he is expected to be their starter in September despite rookie Jaxson Dart's solid performances in the two preseason games."Russ is our starter.
