Can we please see enemy rank and masteries?

I've played a lot of normal games and have seen bronze players being matched with teams as high as diamond. Just got a platinum Riven on my team who carried us to victory, but how would the 1/15 Yasuo know? Their entire team was flaming him until I told them our Riven was platinum material.

Please Riot, I'm tired of putting every name under op.gg to see their current rank. If I lose I want to know it was because I lost to a better opponent and not my mistakes.
