3:10 PM PT -- Jets head coach Robert Saleh says he has absolutely no issue with Echols getting Brady's signature following the loss ... even if the optics of it weren't the best.
"I have no problem with it," the 42-year-old said. "Not at all."
Saleh told reporters that he believes Echols "cares that we lost." He also called the rookie's request to Brady "ballsy."
"To be able to pick off a guy like Tom Brady," Saleh added, "I'm not sure how many guys can say that."
A New York Jets rookie was so fired up to have competed against Tom Brady -- he straight up asked the GOAT for his autograph on the field ... despite losing the game in heartbreaking fashion just minutes prior.
