15 College Football Games that should be happening 1-5

It's been longer than I intended, but I did want to finish the series of 15 college football games that should be happening that currently are not before time moved too far along and I forgot to finish the series!!!
6-10 are here and 11-15 here.

Anyway, here are my top five that need to be played every year...

1) Texas vs Texas A&M

The top game that needs to be played and still isn't on the schedule ruined the college Thanksgiving tradition between the Aggies and Longhorns over issues between the schools ranging from the Longhorn Network to Big 12 problems and eventually sent Texas A&M out of the Big 12 and into the SEC.
The bad blood is so thick between this two that the series that made so much money for the pair went by the wayside and doesn't seem to be returning anytime soon.
Neither seems very interested in renewing the rivalry, but neither's attempts to replace it on Thanksgiving weekend (A&M vs LSU on Thanksgiving Saturday and Texas alternating years with TCU and Texas Tech on Thanksgiving Day) have clicked as anything more than secondary rivalries.
This one really needs to return...

2) Kansas vs Missouri

The hard feelings in this one might be even worse than Texas-Texas A&M even though the situation was similar as Missouri left the Big 12 for the SEC.
This longtime border war likely will be DOA until ironically the person that seems to have taken this the hardest leaves-Bill Self of Kansas-the BASKETBALL coach!
Neither of these teams are generally football powers, in fact, Kansas usually stinks and Missouri is a mid-level SEC team on an average to good year, so it's not like losing this game costs anyone national implications.
Still, this is a game that is huge to Missouri, a team without a natural rival in the SEC and costs Kansas one of the two teams that their fans considered rivals, so it is still a loss to the game...

3) Penn State vs Pitt

This is one that is currently being played in a four-year contract (2018 will be year three), but there is not a future agreement and it's unknown if there will be another contract signed in the immediate future.
Penn State has been the holdup in the past as far as playing this game as they wanted to have two home games for every one home game for Pitt (similar to their past dealings with Temple on the eastern side of Pennsylvania), while the Panthers preferred the home and home series, which Penn State agreed to for the current four-game series.
Pitt has much prestige than Temple and isn't going to settle for a contract like that, so if that is the only offer, they aren't likely to play again for a while after 2019.
It's too bad as the best two teams in Pennsylvania need to play every season...

4) Pitt vs West Virginia

However, if that game cannot be played and Pitt is able to play the Backyard Brawl again every year against West Virginia, that's more than a good enough replacement.
The two neighbors in many ways are even bigger rivals than Pitt and Penn State, share former conference rivalries going back through multiple leagues and frankly just plain hate each other.
I'm not sure if you asked Pitt fans which they'd rather play each year that West Virginia wouldn't come out the winner in a fan vote.
As for the Mountaineers, who seem to think they are above their in-state rival in Marshall and pull on the Herd what Penn State tries to with to Pitt, they likely consider Pitt their biggest rival considering they are stuck in a league that the nearest team is the Iowa State Cyclones, not exactly a heated or passionate pairing there to develop anything at all.
This series was most famous for the 2007 game that saw the second-ranked Mountaineers needing simply a win at home in Morgantown over the visiting Panthers, who had a losing record, to play in the national championship game- only to lose 13-9.
The series is scheduled to return for four games in 2022, so hopefully, there can be a way to keep the rivalry continuing after that.

5) Nebraska vs Oklahoma

This rivalry dates back to the old Big 8 when it seemed like every Thanksgiving Friday the Sooners and the Cornhuskers hooked up in a battle of the Big Reds for the Big 8 title, the trip to Miami for the automatic Orange Bowl bid and often a shot at a national title.
The Nebraska-Oklahoma rivalry was cleanly played with respect, was developed out of two powers that played every year and knew in order to do anything on the national title scene, they would have to go through the other at the end of November.
When the Big 8 became the Big 12 and the two were placed in opposite divisions, the heat was placed off the stove a bit and when Nebraska left for the Big 10, the two schools haven't played since.
Considering that neither school has a natural non-conference rival, a long-term series between the two would be a great fit.
The schools will play home and home in 2021 and 2022 and then again in 2029 and 2030
