Below are 35 mock drafts and their guess for the Ravens pick at #8. I last ran an in depth 'munch' of the mocks in 2005 -- and that year the top pick that year was Mary Clayton. I have doen my own informal munches since and the results have been pretty accurate. This year, most of the 'experts' say we're going to select Matt Ryan, QB Boston College. We'lle find out on the 26th.
