One of the 90s expansion teams in Major League Baseball. Based in Denver, they play at Coors Field by "Denver Rules" - the altitude causes the ball to travel "15%" farther, a boon to offense. The ERA of pitchers, however, inflate like an errant flotation device.
A former NHL team (begun as the expansion Kansas City Scouts), once coached by Don Cherry; they later became the New Jersey Devils. People still refer to the Colorado Avalanche as "the Rockies", in moments of brain cramp.
