There is not limit on how many coaches you can be mad at. Just because Diaz is worse than Rumph, doesn't mean you need to go out of your way to defend him.
Do you not follow the board? Our Oline, reciever, and QB coaches have all been fired and there are way more threads about those positions than people ripping Rumph. Linebacker I agree, but the slurpers won't dare question Manny.
