Mike Pennel expects Aaron Rodgers to be "back with a vengeance" this season but struggles to split the 40-year-old from Patrick Mahomes, having played with both quarterbacks.
Rodgers joined the New York Jets from the Green Bay Packers in a blockbuster trade last year, only to rupture his Achilles in Week 1 and miss the remainder of the 2023 season.
With Rodgers now fully fit, the Jets are expected to be a major force in the AFC when the 2024 campaign gets under way this week, as they look to halt a miserable run of eight losing seasons in a row.
Kansas City Chiefs tackle Pennel spent three years alongside Rodgers in Green Bay, playing 37 games through the 2014, 2015 and 2016 seasons.
Asked if he feels Rodgers has something to prove this year, he told Stats Perform: "Absolutely. I think that's why Aaron still does it. He's a highly competitive person as well.
"He wanted to succeed and with how the Jets were set up last year, it was very, very, very unfortunate how the season began and turned out because they were going to be a formidable team in the AFC.
"I know he's going to come back with a vengeance and he's prepared himself to do so. He has a lot in the tank.
"He learned from [former Packers and Jets quarterback] Brett Favre. So we've at least got about five more years of Rodgers, right?"
Pennel has plenty of experience of playing with generational QB talents, having also teamed up with three-time Super Bowl winner Mahomes through two separate spells in Kansas City, the first spanning the 2019 and 2020 seasons before he returned to the team last October.
Rodgers has thrown for 59,055 yards and 475 touchdowns in 231 games through his 19 years in the NFL.
Mahomes, meanwhile, has already accumulated 28,424 yards and 219 touchdown passes through seven years with the Chiefs, and just six as their starter.
Mahomes' 2023 figures of 4,183 passing yards and 27 touchdown throws were his second-worst since becoming the Chiefs' starter in 2018, after the 2019 campaign (4,031 yards, 26 touchdown throws), yet he still came up trumps when it mattered to lead the team to Super Bowl LVIII glory.
Pennel believes Mahomes' mobility sets him out from all other quarterbacks, but he struggles to split him from Rodgers, who he sees as having a huge influence on others to play the position.
"I think Aaron Rogers, he has crazy arm talent, you know, he was the innovator of the no-look pass and coming out of the gap on scramble and things like that," he said.
"Pat's just a killer, man. I'm telling you about his mobility, but gosh, I mean, I feel like he's like the Ricky Bobby of the NFL!
"He's got the first or his last, you know what I mean? He has a different switch."
