First of all I would say SS/FS is the second biggest need next to RT. We allowed 300 yard passers I blieve 7 times and where 21 in pass defense (6th in run) mainly because of the lack of a good coverage safety. Say we choose not to go safety in the first round as this is a deep class for safeties. I would like Thomas at 13 or 16/17 but we have a chance to fill two other positions with someone like Bulaga/Spiller or Bulaga/Graham or Bulaga/Iupati. With Goldson playing FS but looking more like a SS we also have the option of getting a FS or SS. If we want to get Thomas (FS) at 13 and put him there and move Goldson over we can. If we want to address other needs we can and get a SS later that works too.
Keep in mind these guys would come in and start for Roman/Michael Lewis and would be picked in the specified round.
