I just got done going over all the Mock Drafts that I could find (updated 16 or 17 Feb 2010) and the breakdown is as follows:
Price - DT - UCLA: 8 selections.
Thomas - S - Texas: 7 selections.
Spikes - LB - Florida: 4 selections.
McClain - LB Alabama: 2 selections.
There were 7 other players with 1 vote each.
Not surprisingly, there was only 1 mock draft that had us selecting a offensive player and that was Buluga.
As far as I am concerned I would prefer a true ILB but I am not sure that any of those available will transition to a true MLB at the NFL level so taking a MLB in first round would be a mistake. So based on that, I say take the S first and than start filling in as needed or BPA after that!.
