The Offensive Line doesn’t need any other position to be good. Every other position needs the Offensive Line to be good.
The most important position group in football.

Most OL coaches know what they want their line to look like in August.
The question is: what are you doing in June to get there?
Today’s emphasis:
• Stance
• First Steps
• IZ Combos
• Sled Work
Simple. Repetitive. Effective.
The fundamentals still matter.

Five different personalities.
Five different strengths.
Five different stories.
One unit.
That’s what great offensive lines become.
