I hear ya 43...........
Matthews back spasms, well his body has been through it before.......Stretch, Ice and rest.....He'll be fine. It's been a while since he's had live action.
One thing.......Matthews give us experience. When he got his sack on Sunday, he did not go for the fake inside, he lowered his shoulders, gathered his feet under his hips and wrapped up Newton. That's called "oldschool" NFL experience. He did not run fast out of control, reach for Newton and miss that tackle. He was under CONTROL.
That's what Matthews and Weddle are going to bring to this defense.........Solid, fundamental football.
