Belicheck and Brady are very successful and win allot. That's because they are really good and work really hard.
Some folks tend to hate winners and hate success. They hate winners so badly they make up silly stuff. They make silly claims and silly accusations.
That's cause they are loooooooosers.
No offense. 
I am a big patriots fan and have been for a long time because they are a class act. And i like winners and winning. I respect and admire winners. As opposed to being JEALOUS of them.
The patriots are the anti-raiders.
