According to that noted bastion of knowledge Wikipedia, the "rule of three" is a principle of writing that suggests things grouped in threes are funnier or more effective in film, in speeches or on the page.
The NBA's obsession with the rule of three captured widespread attention when LeBron James and Chris Bosh joined Dwyane Wade in Miami. Three years and two championships later, other organizations are still fighting to achieve similar results.
In college basketball, a strong leading trio can be every bit as important as in the pros. However, in the one-game pressure cooker of the NCAA tournament, even the best alignment of stars can get bounced prematurely if two or all three have a bad night.
As we head into the 2013-14 season, these programs look like they have talented threesomes that can carry them deep into March, or even April. How the trios will actually produce is anyone's guess, as is whether it will even be these particular groups of players who get the job done for their teams.
These teams, however, should be expected to achieve great things this season behind their leading men, whoever those leading men may be.
