No, it's a fact.
According to ESPN, Osa was 4th in PRWR among DTs last year. In 2024, ESPN says he's 16th PRWR among DTs. That ain't top 10.
PFF has him 25th overall among DTs, 9th in pass rush. A good pass rusher who's mediocre against the run.
All that indicates a pretty good DT, not a star. He does very little to protect Micah, it's Micah opponents scheme for, not Osa. Osa gets the benefit of playing with MP, hardly vice versa.
That Osa will get $10m/yr vs MP getting $35m+/yr tells the real story, not the phony one you're trying to tell.
