Spo and Pop: The coaching matchup in the NBA Finals may be as important as the on-court play

Stars will be everywhere in these NBA Finals. The "Big Three" from Miami. The "Big Three" from San Antonio. A four-time MVP in LeBron James, a four-time champion in Tim Duncan.

Then there's Spo and Pop, a pair of known-by-one-syllable coaches.

Miami's Erik Spoelstra wears sharp suits and is a stats guy; San Antonio's Gregg Popovich often forgets to wear a tie and probably knows more about wine than most sommeliers. Outwardly, they seem much different. Deep down, they're probably more similar than anyone would expect.

Spoelstra is looking for a second consecutive championship. Popovich is going for his fifth title, and could join Phil Jackson as the only coaches to lead teams to championships in three different decades.
