The Titans had a power running game, some play-action success and even a defensive stop down the stretch.
It also may have bolstered Munchak's shaky job security.
"The second half was finally how we wanted to play," said Munchak, whose team had lost eight of 10 games since September.
The key plays, though, came from Washington and the defense.
"We were down 10, playing on the road again, not playing as good in the first half as we had hoped, and all of a sudden this thing could have gone the other way," Munchak said. "It didn't. We're not happy with this season. The best we could do is to finish out the season by beating two division teams. We got one today, finally, and we'll be doing our best to get one at home next week."
Tennessee closes the season against lowly Houston, and winning out could help Munchak's case.
"There were a lot of reasons it was an important game for us," Fitzpatrick said. "Just the locker room after, to get that winning feeling back, to be able to get in victory formation at the end of the game and take a knee, that's the kind of stuff you want.
"We haven't been able to feel that for a long time."
The game was one of three on this weekend's NFL schedule with no playoff implications. But it proved to be entertaining - thanks mostly to retiring Jacksonville center Brad Meester.
Offensive coordinator Jedd Fisch called a screen play for the 14-year veteran who announced Wednesday that Sunday's game would be his home finale.
"The thing that ran through my head was 'Don't drop the ball,'" Meester said. "I knew I would catch a lot of flak if I got open one time in my life and I dropped the ball. That was the one thing I was focusing on is catching it. I caught it, got a few yards, would have loved to have scored. That's something I will always remember."
Thing got a little ugly after the catch, maybe expected for someone making his first career reception.
Meester ran right into Nwaneri's backside.

"I couldn't figure out what to do," Meester said. "Am I going outside? Am I going inside? Is he moving? I stuck there for a while and finally went inside and there were a couple of guys waiting for me. I was excited to know I got the first down."
