FPL didn't even exist so they didn't get S1mple from there, he developed at the old way like NiKo or electronic did (small local teams until they jumped on something bigger). Same goes for Twistzz that already was on Tectonic before FPL even launched on America.
But let's move beyond that, players that almost only have FPL experience are not what you usually get to win big events and climb the ranks. Broky may be fine for a team like Windigo, but I wouldn't pick him up if I'm aiming to beat teams like Liquid or Astralis. You can call it an upgrade if you want, but no one would have done room for him even for a Top 50 team before this trial on FaZe.
