Mike Mularkey's job security in Jacksonville, along with his general manager's, looks to be much more at risk.
"We got a glimpse of what we should be capable of doing more regularly on Sundays," Munchak said.
Darius Reynaud scored on two punt returns and Zach Brown returned two interceptions for touchdowns all in less than 5 minutes, and the Titans (6-10) finished by winning two of their final three games. Reynaud also became the first player in franchise history to return two punts for TDs.
Titans owner Bud Adams will decide if that's enough to keep Munchak with two years left on his contract after Tennessee set a franchise mark for most points allowed in a season with 465, worst in the NFL this season.
"It's about winning football games and believe me, he's not going to keep me in the job just because I've been here," Munchak said, who has worked for Adams for 30 years as a player and coach.
"I think it's all about business, and it's about who can do the job. Who do you want representing your ball club? And I feel that I'm the best person for that job."
The Jaguars (2-14) wrapped up their worst season with their 12th loss in 13 games.
Now owner Shad Khan has to decide whether to fire general manager Gene Smith and possibly Mularkey. Their last best hope for this season was Kansas City upsetting Denver Sunday so the Jaguars could grab the No. 1 draft pick, which did not happen.
Mularkey dodged the question when asked about their futures.
"We all work extremely hard, and everybody has from Gene on down, and not to have any reward at all from these games it's been difficult," Mularkey said.
Fans showed their unhappiness with Tennessee's second losing season in three years by staying away, but the Titans at least made it interesting as Reynaud also set a franchise record with 160 yards on punt returns to go with his TDs of 69 and 81 yards.
Brown scored his two TDs after dropping another possible interception in the second quarter.
"We had total control of what we were doing and we were moving the ball, so it's on us," Henne said.
But Tennessee also sacked Henne seven times and finished with three interceptions.
The Jaguars made Keith Toston the fifth different running back to start a game this season, and he had a career-high 66 yards on 12 carries by halftime as the Titans missed tackles and dropped three would-be interceptions. Toston finished with 74 yards.
The Titans took the lead for good in the span of 75 seconds as Brown picked off a Henne pass and returned it 79 yards for a touchdown with 1:48 left in the second quarter.
The Titans finally forced the Jaguars three-and-out to open the third quarter, and Reynaud made franchise history by returning his second punt 81 yards as he first went to his right before reversing back to the left and going up the sideline with rookie Coty Sensabaugh throwing a key block. That TD put the Titans up 28-14.
"When I saw Coty, my eyes just got big," Reynaud said.
Two plays later, Tommie Campbell deflected a Henne pass that Brown picked off and ran 30 yards for his second TD and a 35-14 lead.
"The first one I dropped it, but coach told me that he was going to throw me another one," Brown said. "I was just waiting for me. He threw it to me two times."
