Precious few are worth Mahomes money, Dak's not alone in that. Though what someone's "worth" can be defined as what someone will pay. Is a high end Ferrari "worth" hundreds of thousands or even a million dollars? Not to me, when a $150,000 Corvette is the equal, or nearly the equal, of the Ferrari, performance-wise. (Looks are nearly entirely subjective, can't really speak to what people think about that). I couldn't say the Ferrari is worth it. But people do pay it, obviously to them it is "worth" it. If Dallas did pay Dak Mahomes money, then by some definitions he would be "worth" it.
Actually I don't think Mahomes is worth his contract, either, over $140,000,00 guaranteed, the injury and other risks are big, for an NFL player. Basically the Chiefs are betting the house that Mahomes can deliver at least another 3 SBs, otherwise he's getting paid a huge amount of money for a pretty good career, but not an exceptional one, which $450 million should buy you.
As far as the "200+" is concerned (and I'm one of them, though I did say I'm speaking to this year only at this time), that is, according to the results so far, over 3/4 of the voters. If you don't share their opinion, fine, but dissing over 3/4 of the people who voted isn't necessary or useful....
