The dust has begun to settle on conference realignment.

In the SEC, it feels as if Texas A&M and Missouri have been part of the conference for a decade, with the Aggies contributing a Heisman Trophy and Johnny Manziel and the Tigers claiming two SEC East crowns.

Still, the historical damage of national realignment can’t be overlooked. There are some great rivalry games no longer being played, particularly between those two programs and their former Big 12 competitors.

Here are 10 of the games killed by realignment that we miss the most.

Lone Star Showdown (Texas vs. Texas A&M): These teams have played 118 times. This is a double-edged sword. The Aggies now are good enough and powerful enough to make this game must-see TV nationally. But that’s in part due to A&M’s move to the SEC. TCU and Baylor currently make strong cases as the best football program in Texas as well, but the Longhorns-Aggies game is the headliner. Bragging rights are such a part of the culture in Texas, and it’s sad that we can’t see the two biggest Texas programs face each other.

Border War (Missouri vs. Kansas): The average SEC fan doesn’t realize the pure hatred that saturated this rivalry, which started due to guerrilla warfare and actual killings during the Civil War era. A legitimate argument can be made that, while not as significant to the national landscape, the hatred here rivals the Iron Bowl. (At one point during the more politically-correct era, before Mizzou moved to the SEC, the teams changed the name to the Border Showdown.) The game remains the second-most played ever, as the teams have met 120 times on a football field.

TCU vs. Boise State: The Horned Frogs resurrected in a mighty way last season in the Big 12. But when TCU and Boise State dominated the Mountain West Conference as the upstarts looking to crash the BCS for a few short years, it was as must-see TV as any non-BCS conference matchup.

Colorado vs. Nebraska: The Buffaloes and Cornhuskers dominated the Big 8 for years and years in the late ’80s and early ’90s. CU has struggled as much as any power-conference team in recent years, and Nebraska has languished as a good, not great national program. But this game at one time played a role in the national championship every single season.

The Holy War (Utah vs. BYU): A notch better than the Utah-Utah State rivalry and part of the Beehive Boot, this game halted when Utah moved to the Pac-12 and BYU became independent. The teams plan to rekindle the game starting in 2016, but the ’14 and ’15 seasons represent the first stopping point in the game since the Cougars did not field a team 1943-45 during World War II. Both these teams usually hover near the Top 25. There’s a lot of passion and sub-culture hatred between the two football programs as well.

Battle of the Brazos (Texas A&M vs. Baylor): Who wouldn’t want to see these two offenses race each other to 50 points once per year?

Victory Bell (Nebraska vs. Missouri): Both programs have hovered near the bottom third of the Top 25 in many of the last five seasons. What would you rather see: Missouri vs. Kentucky/Vanderbilt/South Carolina? Or Missouri vs. Nebraska?

BYU vs. TCU: This Mountain West showdown only lasted from 2005 to 2010, but it was fun. The Cougars usually field a strong offense, and Gary Patterson’s Horned Frogs featured outstanding defenses. It made for an interesting matchup between a pair of feisty teams.

Nebraska vs. Kansas: It’s bad enough that the Jayhawks have had to weather the Turner Gill and Charlie Weis eras. KU also lost its two primary rivals due to conference realignment. When the Cornhuskers left for the Big Ten in 2011, the Nebraska-Kansas game was the longest interrupted series in college football. The teams played every year from 1906 to 2010.

Maryland vs. Virginia: The series played without interruption from 1957 to 2013 when Maryland left the ACC for the Big Ten. It’s not the sexiest game on this list, but just another indication of how much historical disruption occurred with all the realignment.
