The earliest a game could happen w/o having to buy out an already scheduled opponent is 2021. However, b/c A&M goes on the road to Colorado and Texas has a road game at Arkansas I highly doubt a deal can be reached b/c both teams are going to want to have at least 7 home games.

2022 probably doesn't work either. That year A&M is the "home" in the game at Cowboys Stadium vs Arkansas. That mean there are only 3 SEC home games. Since the last game was at Kyle Field Texas will surely demand that the series will begin anew in Austin. For them to travel to A&M they've have to pay off USF for a road game they have set up. Normally that wouldn't be too big a deal but it's the second game of a three game series. I doubt they will want to have to pay for two games to travel to College Station.

Just going year by year with the way A&M and Texas have already set up future contests I'd say 2026 is the first year there could be a realistic chance of the series starting back up. Of course that is also fully dependent on A&M and Arkansas no longer playing at JerryWorld every year. If that is still going on 2029 will be the earliest there are no conflicts. Neither side is going to go out of their way to start things back up.

Anytime sooner than that will have to be in a bowl. Knowing both sides and what all SEC/Big 12 bowls there are it will probably have to be an upper tier game like the Cotton. There is no chance in hell it would go down at the Liberty Bowl and the Texas Bowl just doesn't have the prestige.
