Can't you do that for every decade??
Pretty much.
2000s:
NBA: Heat
MLB: Diamondbacks and Angels (plus the Red Sox and White Sox each won for the first time in forever)
NHL: Lightning, Hurricanes (Whalers) and Sucks
NFL: Rams (based on when the game was played; otherwise, this counts for the 90s; first Super Bowl, but won pre-Super Bowl NFL championships), Ravens (original Browns, although they had won pre-Super Bowl NFL championships), Patriots and Buccaneers (4 years in a row)
1990s:
NBA: Bulls, Rockets and Spurs
MLB: Blue Jays and Marlins
NHL: Penguins, Devils, Avalanche (Nordiques) and Stars (North Stars)
NFL: Broncos
1980s:
NBA: Pistons
MLB: Phillies, Royals and Twins
NHL: Islsanders, Oilers and Flames
NFL: 49ers, Redskins, Bears and Giants (these teams all won their first Super Bowl in the 80s, but all except the 49ers had won pre-Super Bowl NFL championships)
Sems like just another reason to post about the Blues...
Can you blame him? Had I been posting here in 2012, you can be damn sure I'd have talked about the Kings at every opportunity.
