Lamar Jackson literally won the NFL MVP award a couple years ago.

After his rookie year, when he didn't start but 7 games, he averaged 200 yards per game passing, or about 3400 over a 17-game schedule. And another 70 yards rushing, or about 1200 for a full season. So that's 4600 total yards.
In terms of efficiency, he finished #1, #7, #17, and #9 in QBR the past four years. And he's only 26 years old. True, he's an injury risk, having missed 5 games each of the past 2 seasons. In 2019, though, he sat out the final game before playing in the playoff game, and in 2020 he only missed a game due to Covid.
Would I pay him $50M a year? No. $40M,
yes, just not fully guaranteed. It would be dependent on the number of games played. I would take him over Ridder, who's unproven, or Aaron Rodgers, who appears to be in decline and a headcase.
