Defense is the big difference this year to last year. They were able control the line of scrimmage and stop the run. Your can't do this year. Combine that with no pressure on Sayin and you have a formula for losing.
The defense needs to find a way to stop their passing attack and get any amount of pressure on Sayin. He's got too much time in the pocket and plays are able to develop down field. They need to tighten up their run defense too.
