The problem: Woods turned pro in 1997 to much acclaim--but not from Singh, whose attitude made it clear that he was immune to Tigermania.
Different strokes: At the 2000 Presidents Cup, Singh's caddie wore a cap that said TIGER WHO? Early on, an irked Woods refused to concede an 18-inch putt, prompting a staredown. When word arrived on the 14th that the U.S. had clinched the Cup, Woods glared at Singh, who'd extended his hand, saying, "There's plenty of golf left.... Don't forget me. I'm right here, looking you right in the eye." Woods wanted Singh to take his full beating, which ended with a Woods birdie on 17.
Since then: Vijay took Tiger's No. 1 ranking last year.
Bobby Bowden vs. Steve Spurrier
The problem: Bowden was the down-home-wisdom-spoutin'
Mouth of the South--not to mention the most successful college coach in Florida--until Spurrier arrived in Gainesville in 1989.
Ain't No Sunshine: In 1994, after Florida State players received free athletic gear from a local store, Spurrier dubbed FSU "Free Shoes University." In '96 he accused Bowden of encouraging his players to take cheap shots. Three weeks later, preparing for a rematch, Bowden told his players, "If I wasn't a good Christian man, I'd tell every one of you to go out and kick Steve Spurrier's ass."
Status: With Spurrier back in the college game at South Carolina, expect more sparks.
Kurt Busch vs. Jimmy Spencer
Why they're fussin': Good ol' boy Spencer, 47, has toiled in mediocre rides for 15 years. The brassy Busch joined one of NASCAR's elite teams, Roush Racing, at age 22.
