Of course if all NFL players tried out for wrestling the talent pool would be much larger and the quality of wrestlers overall would go up. I don't think anyone is arguing to the contrary. To what extent is the question. It might not be quite as clear cut as some think. "Talent" is not "talent". Giant NFL players suck at cross country, the Tour De France, long distance swimming, skiing, I could go on and on. Many would suck at wrestling too and not have the flexibility, endurance, mental toughness etc... but of course some would be great at it and be champions.
Are Jax and Vega national champions because of their freakish strength? Nobody their size plays in the NFL or the NBA so the talent pool is massive for them. sShouldn't all the small muscled up freaks of the world be destroying these two?
