If Miles, that weird horse-head guy who trots the field during Broncos games, was sent to the glue factory, and Dinger, the Rockies' pathetic faux Barney, sank into a tar pit, many sports lovers in these parts would cheer. But were Rocky, the Nuggets' coolest cat, to head for the hills, all of Denver would go into mourning, and rightfully so. For years, Rocky was pretty much the only reason to attend a Nuggets game, thanks to his athletic stunts, crowd-rousing antics and wicked sense of humor -- and even though the team has been playing better recently, on a night-in, night-out basis, Rocky's performance is still more consistent than that of the hottest players. When he shoots, he scores -- even if the ball doesn't go through the hoop.
