Not worth more than 6th or 7th round. He does make Spectacular catch or two, other than that is not a consistant threat. He might be even a FA possibility as I am not convinced of his spead either.
It doesn't help that Chad Henne is pretty inconsistant with his accuracy. I don't know whats with Michigan QBs, since Drew Henson, its been up and down QBing there. John Navarre was the same way and now Chad Henne. Both have occasional great games or great throws then they have where the heck are they throwing kind of throws next.
