This is awesome, Trejan Bridges 2019 5-star WR throws the horns down after a scoring a TD in last weekends playoff game and got flagged. Cant wait to get him and Wease on the field next year.

But here's what I don't understand:

What has "HORNS DOWN" got to do with his high school game.

It makes no sense to throw a flag for it.
