Just my opinion, but it's more luck than skill with roto hoops. Not that I've been particularly successful at it.
Plus, the season is so long, and the regular season isn't the most exciting. Not so many people watch regular season NBA, but lots watch the post-season. Hockey is pretty much the same. In baseball and football, the regular season means so much more. And personally, for all the fantasy sports I've done, I can't say I've ever been tempted to do golf, hockey, or NASCAR.
I would vote to pass on hoops.
