Is there a way to weed out the "fake" plat rank guys?

Look, you champ & higher guys can post all about looking myself in the mirror, which I totally understand.

But there are plat guys in comp that you just KNOW just had a pretty lucky 10 game unranked run & BOOM theyre automatically placed in plat. Its pretty easy to tell who they are just based off how smart they rotate & position themselves & space the field.

Again, I'm not complaining about my lack of being able to win, but I would at least like to have some sort of idea of how experienced some of these teammates of mine are so I know how to work with them better.
