"I apologize for my language because I was going to say we got our butt kicked, but we got our a-- kicked," Ryan said. "There's no two ways, ins or outs about it."
Ryan was so angry he told the players to go home for two days of soul searching, giving them off Monday and Tuesday. The Jets (2-2) have a long week because they don't play until next Monday night, a home game against the undefeated Houston Texans.
"It's unacceptable," Ryan said. "We've got to look at it. It starts with the coaches. The players aren't going to be in Monday or Tuesday. They have to dig deep and look down at themselves. As coaches, we need to look at what we're doing."
Ryan had a right to be upset, as the Jets suffered their third-largest shutout loss at home in franchise history, the worst since a 37-0 loss to the Buffalo Bills in 1989. It wasn't the most lopsided loss of the Ryan era; the Jets lost to the New England Patriots, 45-3, in 2010, but that was on the road.
This latest debacle came in front of the Jets' home fans, not that there were many left in the fourth quarter. The mostly empty stadium was filled 49ers fans at the end of the game, chanting, "Let's go Niners!"
"It's your worst nightmare," Jets defensive tackle Mike DeVito said.
Ryan also apologized to the fans.
"Our fans deserve a lot better than this," he said. "I know right now we're not even close to being one of the better teams in this league, not even close."
Ryan was galled by the defensive performance. The Jets, who began the week ranked 28th in run defense, allowed 245 yards on the ground -- the most in 52 games under Ryan. Remarkably, nine different 49ers carried the ball, averaging 5.6 yards per carry.
"I've never given up so many rushing yards in my life," Ryan said. "I can't remember getting beat the way we got beat. I don't think that's ever happened."
Ryan ripped the offense, the defense and the special teams, which allowed a blocked punt on a "one-man rush," he said.
"I'm not ready to make a quarterback change," he said.
A few longtime Jets said it was the angriest they had seen Ryan in a long time. Wide receiver Chaz Schilens, a newcomer, said Ryan was "disappointed" and "angry."
"Dudes were angry," Schilens said. "It doesn't even have to be Rex. It's just a really bad loss."
