There are some in the press that think Shanahan is going too far by publicly humiliating him, but I think Haynesworth is pretty much reaping what he sowed. He might not be able to practice until next week, if he he can't pass this stupid conditioning test.
Redskins won't trade him, not this year. If he has a MVP-type year, I could see Shanahan and Allen moving him for a couple of draft picks, maybe a toxic asset swap, but I doubt he goes. He's too good and Shanahan isn't the type you push around.
Word on the street is that Vincent Jackson might be suiting up in burgundy and gold, though.
