2. Cam Newton
Cam Newton took the league by storm early in his NFL career. The first overall pick in 2010, Newton was a dual threat that defensive coordinators dreaded, having to think of ways to limit his impact. The MVP in 2015, he would've put up better numbers with the Carolina Panthers if he had had a true No. 1 receiver who could actually catch the football instead of Ted Ginn Jr.
Unfortunately, all the pounding Newton took as a runner eventually took its toll. By 2022, he found himself out of work. He spent one uneventful stint with the New England Patriots in 2020 and returned to Carolina in 2021 but he's had trouble finding work since then.
More recently, Newton caught flak for calling a bunch of quarterbacks game-managers, including Dak Prescott, Brock Purdy, Tua Tagovailoa, and Jared Goff. Regardless of the validity of his statement, those are all starting passers in the NFL right, while Newton's past his prime.
Having said that, Newton could be good enough to back Beathard up in Jacksonville and even keep the offense afloat for two or three games if he were pressed into action. All things considered, that would be reasonable to expect from your third-string quarterback, the role Newton would get with the Jags.
