In the five years since, both teams have seen their share of successes in the conference, which are highlighted in the videos below.
But what do fans of the conference think of the two? We posed the question on our Twitter account this afternoon.
You can check out some of the responses we got right here!
Missouri is a waste of space. Has added nothing and I hope they leave. Aggies a good add.— Michael D. (@MikeDatTiger) July 1, 2017
A&M and who?— 4th & Jort (@4thAndJort) July 1, 2017
A&M is fun to have in the conference. I wish I could say the same for Mizzou. Feels like conference could have chosen better.— Jay Moore (@Jamoney8874) July 1, 2017
Even though Mizzou has at least won the East once in FB. I still think TAMU fits better into the SEC as far as sports culture.— Kenneth Bruno (@KSBruno9) July 1, 2017
No reason for being haughty. A&M and Mizzou both came in with richer histories than a third of the conference before.— Yontin (@JonathanWaldrop) July 1, 2017
A&M was a good fit. Would like to have had Tulane over Mizzou. That being said, Mizzou should be in West;move Auburn to East.— Rob Robertson (@RobRob9) July 1, 2017
Mizzou is bad at everything but unlike Ole Miss they’ve at least been to Atlanta. A&M a good fit. Nice to have guaranteed W every year. https://t.co/hj3HPwoqjj— Logan Leger (@lleger) July 1, 2017
We seem to like having signed up to be in the same division as Nick Saban, for some reason. https://t.co/ykHUbRzQfP— Doug Keegan (@doug_keegan) July 1, 2017
Once A&M can get it together in football they'll be a full fledged SEC program. Still think the Mizzou add was low value— Dill Meets World (@DilltheTrill) July 1, 2017
It's fine having them but I don't think I'd miss them if they were gone ¯\_(ツ)_/¯ https://t.co/YcGf4opV4x— David Wunderlich (@Year2) July 1, 2017
Do we have the receipts for Mizzou somewhere? What's the Big XII's return policy? https://t.co/7hQ9RmRlIJ— Nic Gulas (@Nic_Gulas) July 1, 2017
Mizzou won division in FB, but East has been weaker than West (no Bama). A&M more across the board success.Both glad out of B12.$$$$. https://t.co/aOy9Ezymyl— Jimmie Snyder (@labayouboy) July 1, 2017
A&M arguably on the rise, Mizzou definitely in a decline. https://t.co/tNJAeNs7RZ— Joe '19 (@chenaggie2019) July 1, 2017
I think both hv bn good 4 SEC. A&M more so and they raised competition level 4 sure. Mizzou not as much but hv bn a decent fit n the East— Loyal2LSU (@Loyal2_LSU) July 1, 2017
I still consider both of them pledges. https://t.co/xg1YJGYhXm— Ashley Purifoy (@LAPurifoy) July 1, 2017
Aggies are fine. Adding Mizzou was the worse decision in conference history. Need to replace them with Clemson, Va. Tech or FSU. https://t.co/AHzHne3tSx— Matt Tyler (@MattVTyler) July 1, 2017
Significantly raised the conferences wrestling profile.— Gaknar (@Gaknar) July 1, 2017
The overwhelming indifference/despising of Mizzou is kind of weird. I mean, they’ve been to Atlanta twice! That’s pretty good. While Missouri, as a state, is far more midwest than south, Mizzou’s a perfectly fine SEC fit. I also went to Mizzou for the final year of the Big 12 and, thus, the transition to the SEC. It takes time to fit in to a new conference, especially one with the heritage of the SEC, but Mizzou will be fine.
