Wendy's 3-Tour Challenge
Which tour wants it more? Nine of the world's best golfers (three each from the PGA, LPGA and Champions tours) battle it out at Lake Las Vegas Resort for charity—and for tour bragging rights. The PGA Tour, which will be represented by Chris DiMarco, Camilo Villegas and Bubba Watson, has won this 15-year-old event seven times, but this year's trio combined for zero wins this season. Even Champions tour team member Fred Funk had a PGA Tour win.

Snowboarding USSA Grand Prix
The tour's 12th season kicks off in Breckenridge, Colo., where 16-year-old Ellery Hollingsworth (right) finished eighth in the halfpipe last year. The up-and-comer, who snagged the women's title for best trick at last year's New Zealand Open with a backside 720 on the 500-foot pipe, is expected to place high in her second pro year.

Dolphins at Patriots
Last year's second meeting between these teams was the last regular-season game New England lost—and, until Sunday, Miami's last win. Now that they've avoided a winless season by beating the Ravens, the Dolphins can focus on ending the Pats' quest for perfection, which only the '72 Dolphins (left) achieved.

Heat at Cavaliers
After the gifts are unwrapped, you could stare at A Christmas Story for the 11th time this month—or watch NBA leading scorer LeBron James, who is averaging 29.4 points, lead the Cavs against a Miami team that's trying to crawl out of the Eastern Conference cellar.

SI PICK OF THE WEEK
No. 5 Georgetown at No. 2 Memphis
After hearing for years that their Conference USA schedule is softer than the Stay Puft Marshmallow Man, two-time defending conference champ Memphis scheduled Big East powerhouse Georgetown (8--0) over the summer to quiet its critics. Now the Tigers (8--0) have to win. Leading scorer Chris Douglas-Roberts (above), who's averaging 18.3 points per game, has already fared well against Big East opponents this season. The junior guard put up a career-high 33 points against UConn in the Tigers' 81--70 win last month.
