Valentine's Day isn't all chocolate and kisses and hearts. Plenty of those hearts get broken. The same is true throughout any Big 12 season. Here's who left a few opposing fans in tears in 2010.
1. Landry Jones. Oklahoma State had him backed up deep in his own territory with a two-point lead and a deafening crowd behind him with less than three minutes to play. He'd already teased them with a pick-six earlier in the game. But Jones connected with Cameron Kenney for an 86-yard touchdown to put the Sooners up by nine points. He later hit James Hanna for a 76-yard score to ice the game after the Cowboys returned the ensuing kick for a score. That's cold.
2. Kenji Jackson. It looked like a fairly harmless hit at the time, one that happens countless times in any game. But late in the first half, the Missouri safety came up to the line of scrimmage and laid a solid hit on Taylor Martinez's lower body. Martinez stayed in the game to finish the half, but didn't play in the second half. Nebraska won, but Martinez's sprained ankle changed Nebraska's season, and he was never quite the same player after he hurt the ankle. Jackson's hit was the gift that kept on giving. If it didn't happen, who knows where Nebraska's season would have finished.
3. The Ames wind. I'll give Iowa State backup punter Daniel Kuehl the benefit of the doubt on this one. If the wind at Jack Trice Stadium hadn't been absolutely swirling, he probably could have completed the pass that would have meant the Cyclones beat Nebraska and Texas in the same season and would go to a bowl game. But the pass floated in the wind, and Nebraska's Eric Hagg intercepted the fake extra point to preserve the win. If it had been completed, it would have put the Cyclones in the driver's seat of the Big 12 North, too.
4. Officials in The Bronx. Adrian Hilburn made the catch, made a defender miss and sprinted 30 yards into the end zone to cut Syracuse's eight-point lead to two with less than a minute to play in their bowl game. He shook off a defender after scoring and saluted a group of K-State fans in the stands who made the trip from one Manhattan to the other for the week before the Pinstripe Bowl. "Wrong move, buddy," one official reportedly told Hilburn. He tossed a flag and the Wildcats' lengthy conversion was incomplete. The dagger!
5. Oklahoma State's defense against Texas A&M. What a cruel, cruel win. The defense struggled a bit and let the Aggies jump out to a 21-7 lead at the half. Then a sack and fumble returned for a touchdown put them up 35-21 in the fourth quarter against the Aggies, a stretch of 28 consecutive points. The defense allowed the Aggies to tie the game, but Shaun Lewis intercepted Jerrod Johnson -- his fifth turnover of the night -- and set up a game-winning field goal to beat the Aggies at the gun. If Texas A&M had beaten the Cowboys, it would have won the Big 12 South outright for its first division title since 1998. What a painful way to go down.
