Texas A&M legend Johnny Manziel was one of the most-electric players in SEC history, winning the 2012 Heisman Trophy as a redshirt freshman.

In that season, Manziel tore through the SEC in the Aggies’ first year in the conference. He redshirted in 2011, though, so he is also familiar with some of the Big 12 venues and teams.

On Tuesday, Manziel weighed in on the news that Texas and Oklahoma are trying to get into the SEC. As you can see below, he had a stern warning for the Longhorns and Sooners:

“Lucky for A&M, we have a 9-, almost 10-year head start on both of those teams being in the SEC,” he said. “The rivalry has been gone for a while, but now it looks like it’s coming back. It’s time to just sack up and go play the game. We’re in a good position. We have a good coach. We have a good team. If they want to come to the SEC and see what it’s all about then we’ll welcome them with open arms. But it is no cake walk and it is not the Big 12, so it should be interesting to see how things play out.”

Oklahoma will be one of the highest-ranked teams entering the 2021 season while Texas continues to rebuild. We could find out as soon as 2022 how the 2 Big 12 powers fare in the SEC.
