I loved Ki-Jana Carter when he played at PSU. Although it should be said that getting injured didn't help his cause. So over-value may be a bit harsh.
Brian Bosworth (growing up in Seattle, I was 12 years old when the Seahawks got him, and as a punk kid, I thought he was cool...sad, but true story)
Rick Mirer (another Seahawk blunder)
and there are a host more, although I can't remember them at this time
