One of the most unpredictable regular seasons on record ends Saturday, with eight of 10 Bowl Championship Series invites still up for grabs — including the two golden tickets to the BCS National Championship in New Orleans January 7.

One scenario for that game is simple and would allow the BCS to put on a rare relatively controversy-free title match. If top-ranked Missouri and no. 2 West Virginia win, they will meet for the championship. If one loses, it will be replaced by no. 3 Ohio State, which has been idle for two weeks since winning the Big Ten.

There’s also an unsavory scenario — in which both Missouri and West Virginia lose — that is probably creating sleepless nights for BCS officials. If that occurs — it’s worth noting West Virginia is a four-touchdown favorite — one of several two-loss teams, or once-beaten Kansas (which didn’t reach the Big 12 championship) could end up in the title game. In other words, cue the complaining.

Here’s a conference-by-conference guide to tomorrow’s relevant games (all rankings BCS):

ACC CHAMPIONSHIP

No. 6 VIRGINIA TECH (10–2, 7–1) vs. No. 11 BOSTON COLLEGE (10–2, 6–2)
At Jacksonville, Saturday, 1 p.m., ABC

In their October meeting, Virginia Tech dominated Boston College for 56 minutes, only to see quarterback Matt Ryan and an onsides-kick bail out the Eagles. The loss all but killed the Hokies’ national-title hopes. Virginia Tech comes in on a roll, looking to secure an invite to the Orange Bowl as ACC champ.

BIG EAST

PITTSBURGH (4–7, 2–4) At No. 2 WEST VIRGINIA (10–1, 5–1)
Saturday, 7:45 p.m., ESPN

This season has proven the folly of assuming the outcome of any game. That said, West Virginia should have little trouble beating lowly Pittsburgh to punch a ticket to New Orleans and the BCS championship. The Mountaineers are coming off their best performance of the season, as they destroyed Connecticut, 66–21, in a de facto conference-title game at home last week. Look for Pat White and Steve Slaton to run wild on Pittsburgh’s middling rush defense.

BIG 12 CHAMPIONSHIP

No. 9 OKLAHOMA (10–2, 6–2) Vs. No. 1 MISSOURI (11–1, 7–1)
At San Antonio, Saturday, 8 p.m., ABC

For the second straight week, Missouri plays what is likely the biggest game in school history as it attempts to get to the BCS title match. The Tigers were up to the task last Saturday night against then-unbeaten Kansas, particularly quarterback Chase Daniel. He completed 40 of 49 throws, likely earning an invite to New York for the Heisman ceremony, as the Tigers won to move up to no. 1 in the rankings for the first time since 1960. This has the potential to be shootout, as both teams are among the top six nationally in scoring offense. Oklahoma has a better overall defense, but neither team is stellar against the pass, so expect plenty of balls in the air and lots of gaudy statistics from Daniel and Oklahoma’s Sam Bradford. The stakes for Missouri, which is a slight underdog, are well-known. An Oklahoma win most likely sends the Sooners to the Fiesta Bowl.

PAC-10

UCLA (6–5, 5–3 Pac-10) At No. 8 USC (9–2, 6–2)
Saturday 4:30 p.m., ABC

ARIZONA (5–6, 4–4) At No. 13 ARIZONA STATE (9–2, 6–2)
Saturday 8 p.m., ESPN2

USC can clean up a convoluted Pac-10 title picture by beating cross-town rival UCLA. Amazingly, the Bruins also remain alive to get to the Rose Bowl, but need to win and get help from Arizona. Both teams have had disappointing years by their respective standards, with injuries a mitigating factor. Both are as healthy as they have been in some time, particularly at quarterback.

Should UCLA win, Arizona State will go to the Rose Bowl if it beats Arizona. The Sun Devils were in control of the conference until USC dominated them on Thanksgiving night. Quarterback Rudy Carpenter was left bloodied by the Trojans’ defense, and if he and the Sun Devils haven’t recovered emotionally and physically, they will fall to an Arizona team that upset Oregon in its last outing.

SEC CHAMPIONSHIP

No. 14 TENNESSEE (9-3, 6-2 SEC) vs. No. 7 LSU (10-2, 6-2)
At Atlanta, Saturday, 4 p.m., CBS

This game lost much of its intrigue thanks to a pair of overtime results last week. Then-no. 1 LSU lost at home to Arkansas in triple-overtime, while Tennessee held on against Kentucky in four extra sessions to keep surging Georgia from reaching the game. As a result, the focus has shifted from LSU playing for a national championship to whether this will be coach Les Miles’s last game with the Tigers. In a widely expected move, Michigan asked for, and received, permission to interview Miles about its coaching vacancy. It is assumed that Miles, a former player and assistant coach in Ann Arbor, will accept if offered.

OTHERS

WASHINGTON (4–8) at no. 12 HAWAII (11–0)
Saturday, 11:30 p.m., ESPN2

Last Friday’s win over Boise State gave Hawaii, the nation’s lone unbeaten team, its first-ever outright WAC championship and put the Warriors in position to receive a BCS invite. A win over Washington, the only BCS-league team on the Hawaii schedule, would make that invitation all but certain. The game is also a final opportunity for Hawaii’s prolific senior quarterback, Colt Brennan, to secure an invite to the Heisman Trophy ceremony. Hawaii should enjoy this moment before what is expected to be a rowdy sold-out crowd at Aloha Stadium — a win means a possible Sugar Bowl date with LSU, where the Warriors won’t find the atmosphere so friendly.
