Only about 1% of the population would think he would be "the greatest on Earth". More likely is he would get destroyed by the liberal media (which would be ironic, considering they're the "pro Black people" party), and he would probably be cast off by the NFL and then nobody would care about him anymore, because he'd have to get a real job and live like regular people (which by the way would be hard to do, since most large employers in this Country are going to very soon have vaccine mandates, if they don't already).
The guy isn't going to be a martyr because he publicly refused to get vaccinated and quit his job over it. Thousands and thousands of people have already done that, and nobody cares about them.
And for what its worth... the people deciding to do that aren't in the class of Lamar. They're not risking millions of dollars to avoid a vaccine. It's honestly not that difficult for a guy making $50K to quit his job over his "principles", because either he'll find another job at an employer who doesn't care, or he'll mooch off government welfare and not be that much worse off. It's an entirely different animal all together for a guy making a couple million a year (especially a young guy like Lamar) to just say "I'm out" and give up all that money (especially the future earnings he's got coming).
Why do you think the idiots over at Fox News get criticized so much? They spew anti-vaccine stuff online, and then the world finds out that most of them are, of course, vaccinated, because their employer makes them get vaccinated and they ain't willing to give up the cash for their "principles".
