The Physical Tools
Rosen checks all of the boxes physically. He checked in at the combine at 6-foot-4 and 226 pounds with a 111 inch broad jump, 31 inch vertical jump, and ran a 4.92 second 40-yard dash time. When you watch him play, he is poised, stands tall in the pocket, and looks so fluid with every pass. His mechanics are flawless.
When you watch his film, he rarely looks off-balance. His ability to set his feet, plant, and drive the ball to his intended receiver with his large frame showcases his arm and quick release. He stands tall in the pocket and will take major hits to deliver the ball.
The California native also often showcases his touch. He regularly puts the ball right where the receiver needs it to be and has a knack for hitting receivers in stride deep down the field. His accuracy to every level of the field blows you away.
If you watched the combine, you saw players with weaker arms throw timing routes where they would release the ball well before a receiver got out of their break to get it there in time. Other players with stronger arms, such as Josh Allen, were able to zip the ball in after the break and were able to compensate. Josh Rosen is a mix of both.
Though a polished passer, Rosen is not an outstanding athlete. He isn’t the fastest, but he is mobile. Think of Peyton Manning or Tom Brady when they are being rushed. They aren’t a threat to take off and run, but they have a unique ability to step up, avoid rushes, and deliver a ball and move the chains.
