I like that. That is our future. I kind of like Roy Wonder, but after most games when I posted about a game I've just said and Roy was Roy.
"Roy Wonder" is clever, but too elaborate. It's not a simple, natural-sounding nickname, like "Magic" or "Air" or "Glide." But this is the new breed that doesn't need nicknames...Kobe, Paul, LeBron, Roy.
I don't like "Roy Wonder" -- too cutesy. Also, for some reason it makes me think of white bread... I think "The Natural" fits best; it's subtle, strong, and understated, just like Roy's game.
"Slow-Mo" would be fitting because of how he looks when he does everything he wants to do, while everyone else just commits the wrong way or falls down. But "slow" is probably not a tag you want to be affixed to.
