The Linebacker position isn’t important.

Is what people say who don’t understand the game.

Linebackers stop the Run.
Cover the Pass.
Blitz the QB.

They’re the heartbeat of the defensive unit.

Took a little social media break but we’re back.

Recap: Had an awesome season, 11-1 record, 2025 finalists, 85 helmet stickers, my brother Dylan and I both made the IYFL All Star Game for our age groups and had a blast playing with the top talent in the league. Blessed 🐅

9/27 against first place Springfield. Got the win. They called me for block in the back here?? 🤨 🙂‍↔️

[Jonathan “JJ” Mann @jjmann020]

9/20 game against our hometown. 7-TFL, player of the game. Me and @GaravelasNik crushed it. 31-0 final score. Whoops!

Put that on a t-shirt.

Linebackers:

Movement skills are key.

LOW.
SQUARE.
DOWNHILL.

Elite Linebackers are efficient movers.
