TEMPE, Ariz. -- It's hard to argue with the numbers.
"Calvin's the best," Arizona receiver Larry Fitzgerald said. "I mean, look at his numbers. It is what it is."
Last season, Johnson led the league with 1,964 receiving yards. Fitzgerald had 798, his lowest total since his rookie season, while catching passes from four different quarterbacks.
Arians began the discussion by saying Sunday's Lions-Cardinals game at University of Phoenix Stadium will feature a matchup between two of the best at their respective positions: Cardinals cornerback Patrick Peterson and Johnson.
"You have to watch what you wish for sometimes," Arians said. "I think an elite player like Patrick, in my opinion, who is probably the best corner in the league, is going against the best receiver in the league."
Fitzgerald, who is in his 10th NFL season, is having a Hall of Fame career. He has more receptions (772) than any other receiver through 141 games. He also was the second-youngest to 10,000 career yards and the youngest to 700 receptions.
But Johnson, in his seventh year, isn't far behind.
Through their first six seasons, Johnson had 7,836 yards compared to Fitzgerald's 7,067.
Peterson, who has been to the Pro Bowl in his first two seasons, said he believes Fitzgerald is the overall best wide receiver in the league but that Johnson took top honors in 2012.
"He's done a lot of great things for his team, and he had a huge success last year hooking up with [Lions quarterback] Matthew Stafford and gaining all those yards," Peterson said. "I would never put another guy in front of my guy.
"I believe Larry's still the best receiver in the game."
In other news ahead of Sunday's game, Fitzgerald appeared on the Cardinals' injury report Wednesday as a limited participant because of a hamstring injury.
He was again listed as limited Thursday but told reporters after practice, "I'm fine."
