Rangers pick will be a late 3rd, and that's a good price for a solid, decent, entirely pretty good NHL defenseman.
Of all the 3rd round picks in Coyotes history, Adin Hill (2015) and Michael Stone (2008) are the only ones maybe more valuable than Maatta. Only a handful of later picks (Yandle, Maccelli, Winnik, Garland, maybe Clifton) are better than Maatta.
