I think the comparison to Vince Grier is interesting. Bill Simmons wrote in his book The Book of Basketball about how the AAU circuit and around the year "coaching" has turned players in to robots who all play the game the same way. Any uniqueness to a players game is coached out of them and nobody is very innovative. Armelin, like Greer, is a guy who plays the game a little different and, therefore, can be much tougher to defend than a guy with similar basketball abilities who plays a more conventional style. Chip isn't as big as Grier, but he's got a uniqueness to his game that reminds of Vince.
