All of these are in order:
NHL: Colorado Avanlanche
NFL: Denver Broncos, and I also really like the Carolina Panthers
NBA: I don't really follow B-Ball as much as hockey or football but it's a tie between the San Antonio Spurs and the Denver Nuggets
NCAA Hockey: University of Denver
NCAA Football: Texas
MLB: I really don't like watching baseball, as much as they suck I guess I'd say the Colorado Rockies
