Eureka!!!-Provisionals MMR Lowering Reasons-Opiinions, Logical Fallacies Found are Welcomed
This is not meant to be a conspiracy theory. I honestly think this is part of the reason they do this.
They lower everyone's MMR, then look for the newer players that manage to climb through the BS of 100+ games to reach Challenger/Master, and then watch to see if they continue to dominate. Then teams looking for newer members (as current team members do the whole "plans for the rest of your life" thing) can pluck these "anomalies" (most won't reach original rank for a little while longer) out of the masses and offer them the now vacant positions/ backups. To be clear Riot doesn't do this, they just provide the environment (extremely competitive, salty/pissed off players wanting to return to their original division) to allow the teams to do this. And also while almost everyone is lowered to increase this competition/engineered accelerated selection(survival of the fittest type stuff)
You may suggest, "Why not just look for people who dominate Solo-Que for a period of time." they do this obviously (Bjergsen for ex.) but the people currently dominating=mostly already on a team. A new guy/girl that can beat these people may be in the game probably exists (the next Faker/Doublelift/place your chosen stupidly good player here) but is, once again extremely rare, and its not as if these people won't fight back. So build a list of potential candidates before it becomes a problem, then look for the ones now dominating from that streamlined list later on as the current dominators move forward (Wildturtle can't do this whole multiple smurfs in top positions forever you realize, but someone already on a team will immediately take the spot though, leaving no room for the newbies unless(again) he/she is god-like.
Disclaimer: Have not played Ranked myself, watched others be crushed by it and this is my current theory for it. Put it in Miscellaneous because you can delete a post that is put there unless its actually vulgar (changed my mind, probably will end up re-posting to Miscellaneous). If anything I think that this is ingenious considering how over time players saturate the system making harder for potential professionals to rise, and this creates room for these unusual people to rise at a impractical/god-like rate, in comparison to their peers.
SIDENOTE: When do you think there will be a female Faker/Bjergsen/etc.? I would say within the next decade or so.
