It's a good 9 minute watch...Enjoy
My greatest source of joy with Rosen is his intermediate and vertical accuracy. It’s a beautiful and consistent process.
To add some perspective to Rosen’s prowess, there are a lot of NFL quarterbacks who lack Rosen’s consistent range and accuracy in the vertical game. When you hear about quarterbacks who can throw the ball 60-70 yards, it’s best to consider the range of distance they can consistently deliver pinpoint throws.
The most common range for NFL quarterbacks is 40-50 yards.
Rosen’s is a tier above.
