I'd argue that Swag is the best banned player around tbh. He was sick before and he's even better now.
And William, the reason SeanGares gets on teams is because he's one of the best IGLs in NA. Also, when C9 went on that sick summer run he was fragging like a God, showing he's not just brains.
He's one of the best because there are hardly any IGL's in NA worth the recognition. Stanislaw and Stewie are examples of good IGL's who are still good at fragging. I feel like Sean spends so much time setting up other players he forgets about himself. The only thing good out of this is that he might help develop Sykler, Twistz, and Sick into better players. We'll see
