Look at the small details in this video. Watch when our running back get hit just past the line of scrimmage. They move backwards. When Bama's backs are hit in the same position they fall forward to are able to keep moving forward. When our receivers are trying to get off the line of scrimmage they are stopped for a second during their release, Bama's are not, Oregon's are not, Florida State's are not. This is a clear indication of talent, speed, and strength.
When we had Jamal, Travis, Travis among others, our back use to get hit and keep moving forward. Our receivers use to get a clean release off the line of scrimmage, making the timing plays more effective.
I have no doubt when our speed and talent is where it should be (the incoming class) we will see a huge difference in the results.
