You don’t think the right side of the line is a problem? The OLine is youngest in the NFL. Takes time. Depth takes time and more than 1 off season. Basically a rookie QB. Takes time. That’s the rebuild. Totally new system. Takes time.
You think any of the Vrabel Titan film on Willis is helping today? That’s the damn point. No one used him properly and the film they had was wrong. They have film. LaFluer is a better coach than Vrabel obviously.
