So in other words, you don't want any supports on your team? Once you figure in the brief games that end in 20-minute surrenders, even a carry might be hard-pressed to average that 133 CS/game (assuming a 50/50 win rate; even HIGHER if one wins more than 50% of the time)
And if you're a pro support? You'll average a CS of like 20-30 per game at most. That means at least 26,000 games played to rack up 80k CS.
Also, win count is a bit over-stated, as even the worst player will eventually win, and hence, eventually even the worst player could get 300 normal wins.
