The ACC and SEC denounced the practice of teams planting a flag on an opponent’s field following a number of post-game fights during practice during the week last.

“We need to come together collectively,” ACC Commissioner Jim Phillips told Yahoo Sports. Ross Dellenger. “We can do things independently as conferences, but we all have to come together and our approach has to be aggressive. This is unacceptable.”

“There shouldn’t be a flag planted. Go win the game and go to the locker room,” SEC Commissioner Greg Sankey added. “If you want to plant a flag, you play “capture the flag,” or you join the army, or you fly to the moon.”

And Big 12 Commissioner Brett Yormark also said the major conferences should “come together to look at these issues.”

The practice became more widespread over the weekend, with fights breaking out during a few games after a flag or pitchfork planting incident, most notably between Michigan and Ohio State. Both teams were fined $100,000 by the Big Ten after their brawl following the Wolverines’ upset victory:

This was not an isolated situation.

NC State and North Carolina players fought after Wolfpack players planted their flag:

Florida State players didn’t appreciate Florida planting its flag:

After the game, Florida head coach Billy Napier called the flag planting “embarrassing to me.”

“We shouldn’t have done that,” he added. “We will not do this in the future, and there will be consequences for everyone involved.”

Arizona State drove its pitchfork into the ground against Arizona, which didn’t sit well with the Wildcats:

The practice has divided opinion.

Some people think that planting a flag is a classless act and that teams should win with a little more grace, even in rivalry competitions. They see this act as a lack of sportsmanship. From this perspective, it’s easy to understand why a team would defend their home field.
