Florida State was left out of the playoffs last year because one player was out. If Ohio State players get suspended for attacking the Michigan players after the game, should they also be left out of the playoffs? Some of the players involved were significant starters.
I 100% support flag planting, or walking on the logo, or whatever as long as it’s not directed at specific people. That’s how taunting has always been handled, and that’s how it should continue to be handled. Home teams rush the field, away teams get to plant the flag (or trident in ASU’s case).
To the losing home team, mind your own fucking business and let people celebrate. The winning team isn’t responsible for their behavior.
