I agree with some of your points. I had to have career ending foot & ankle surgery when I was in the Marines and go through all the steps...different meds, physical therapy, steroid injections, foot in a cast, etc (military doctor's are a joke, glad a civilian did my surgery).
To me, if Schobel needs surgery, this sets the team back and they need to have a plan ready. Last year's excuse for Schobel was that the D-line sucked, this year his injury, how long are the Bills gonna keep this guy & his high price tag before they cut him loose? If he can ever return to his pro-bowl form, then that would be great and I'll be the first to admit I'm wrong about him. But IMO, he's damaged goods and is highly overpaid.
