I don't know why I've decided this be my first fanpost/comment/contribution to Blazersedge (as I've been coming to this site religiously for the last five years), but I'll just suppose it's because I'm hoping Lillard will provide some light in the catechism of doom we found ourselves in after last season.
Anyhoo...nicknames: they're inevitable, fun and provide a connection to players on the team (no matter how frivolous they actually are in reality). Why not have a fanpost discussing them? Obviously, the only rookie really warranting one right now is Lillard, but maybe readers have thought up some clever nicknames for Leonard and Barton as well. I like to have a couple for each player so nothing needs to be unanimous obviously. The more creative and fun to say, the better.
The name I've dubbed Lillard, if you haven't noticed from my name already, is Lillmatic (from Nas' album Illmatic...one of the best hip hop albums of all time). It also implies that he's "automatic" which, if looks aren't deceiving (wait, they are?) then he may fit the bill.
I've seen "The Omen" mentioned and DLill (which, like DRose or DWill doesn't, to me at least, qualify as a nickname). I'm sure there are many more ideas out there so leave them in the comments if you have any. Big ups!
