26 seems to be the magic number when it comes to professional losing streaks. Tampa Bay of the NFL lost 26 games over two seasons. The 1889 Louisville Colonels lost 26 for the longest slump in professional baseball and now the Sixers have tied the Cleveland Cavaliers with 26 losses. Then as I was searching around, I stumbled across Division III’s Cal Tech Beavers. Since 1961, they’ve only won eight conference games.
