BYU plays a football game late tonight, but there's even more suspense for Cougar fans this afternoon - the Heisman Trophy Award (4:30 p.m., Ch. 5) will be presented.

As all true-blue fans know (and even red, purple and navy blue fans too), Cougar quarterback Ty Detmer is one of the frontrunners to win the award symbolizing college football's best player. But there's always the possibility that that fellow from Notre Dame might stand in Detmer's way. (What was that guy's name? Missile?. . . . Rocket? . . . Over-rated? . . . )One word of warning: The award show is half an hour long, and the first 20-25 minutes will be filled with highlights of the candidates and odes to past winners. The actual announcement will be a whole lot closer to 5 p.m. than 4:30 p.m.

Of course, whether Ty wins the trophy or not, he'll still be leading his team against the Rainbows when the BYU at Hawaii (10 p.m., Ch. 5) game gets under way.

Now let's talk about the Cougars' national-championship hopes. Slim as they are, BYU could still take three steps toward the No. 1 ranking if things go the right way in televised games today:

Texas A&M at Texas (10 a.m., Ch. 5) - If A&M can knock off Texas, not only would that ruin the Longhorns' title hopes but it would make the Aggies a much more credible foe for BYU in the Holiday Bowl. Conversely, a win by Texas would probably move the 'Horns ahead of the Cougs in the polls, and if Cotton Bowl foes Texas and Miami are both ranked in front of BYU, that pretty much ends any hope of the Provo team winning the national championship.

Georgia Tech at Georgia (10:30 a.m., TBS) - The Bulldogs are only 4-6, but they're at home. If they can knock off Tech, another title contender bites the dust.

Miami at San Diego State (2 p.m., ESPN) - OK, this is a longshot - a long longshot. But if lightening strikes and the Aztecs win, the Hurricanes can forget about finishing No. 1 again. (And, by the way, ESPN decided to pick up this game instead of BYU at Hawaii - meaning tonight's game remains a 10 p.m. MST start.)

So get the popcorn and the remote control ready. And if you sit for this whole college football marathon, you'll only be at it for about 16 hours - from 10 a.m. until the BYU-Hawaii game ends about 2 a.m.
