Yet if the star receiver realizes that if he can't end his career holding the Lombardi Trophy, catching a touchdown pass to win the NFL receptions title in a dominant victory wouldn't be a terrible substitute.
Carson Palmer threw touchdown passes to Jeremy Ross, Darren Fells and Fitzgerald, and the Cardinals wrapped up a frustrating season with a 44-6 victory over the freefalling Los Angeles Rams on Sunday.
Fitzgerald caught five passes and took the overall NFL lead with 107 catches in perhaps his final game for the Cardinals (7-8-1).
He intends to take his time with his decision on retirement following his 13th NFL season, even after he returned to the field in the fourth quarter for that TD grab and chants of "Larry! Larry!" from the Coliseum crowd.
"I always stay in the moment, and the game wasn't over yet. I was still honed in and focused on what we had to accomplish. ... I approach the offseason the same way all the time: It's jet-setting time."
The Cardinals missed the playoffs one year after reaching the NFC championship game despite an offense and a defense ranked in the top quarter of the league.
Arizona still finished the season strong with wins over NFC West champion Seattle and Los Angeles (4-12), which has lost seven straight.
"I'm very happy with the way we played in the last two weeks," coach Bruce Arians said. "But I'm unhappy that we did not win four or five games in the fourth quarter (earlier in the season)."
The Cardinals' defense sacked Jared Goff seven times and allowed just 122 yards by the Rams, who wrapped up their homecoming season with their worst record since 2011.
"I'm not sure there is much" of a bright spot to this season, Goff said. "Maybe that we have a change coming that is going to be positive and bring a lot of positive energy."
With a blowout win capped by Justin Bethel's 68-yard TD return of Sean Mannion's interception with 8:06 to play, the Cardinals also got even for their 17-13 loss to the Rams in Week 4, one of several early flubs that doomed an injury-filled roster to an early winter.
Los Angeles was 3-1 after that road victory, but lost 11 of its final 12 games in an incredible pratfall.
Interim coach John Fassel went 0-3 after replacing the fired Jeff Fisher, who presided over the Rams' relocation and the franchise's 13th consecutive non-winning season.
"This isn't the culture you want to live in," offensive tackle Rodger Saffold said. "I've been here seven years and still haven't had a winning season. I know I've worked hard enough to deserve better."
Despite managing just 77 yards of offense in the first half, Los Angeles kept Arizona's lead to 16-6 with a handful of big plays, including a blocked punt by Chase Reynolds.
David Johnson left the field on a cart in the first quarter with an injured left knee after getting tackled awkwardly, but Arizona's star running back appeared to be able to put weight on his leg when he returned to watch the second half from the sideline. Johnson gained 100 yards from scrimmage in each of the first 15 games for the Cardinals while compiling the franchise's first 2,000-yard season. The Cardinals had no immediate update on his prognosis. "We're praying it's all positive, and I can block for him in the Pro Bowl in the next couple of weeks," Fitzgerald said.
