The Broncos are learning what so many prior Super Bowl champs have found through the years — how difficult it will be to repeat.
The Aqib Talib shooting last weekend is the latest thing to hit Denver during a turbulent offseason. The Broncos have lost their top two quarterbacks and several other key starters in free agency, and they have not yet put on full pads.
The NBA, perhaps due to smaller rosters with less turnover and lower injury factor, gets repeat champions more often. We likely will see another soon with the Warriors. In the NFL, it's been 12 years since the Patriots won back-to-back titles in the 2003 and 2004 seasons.
