Which draft pick seemed like a reach at the time, but turned out to be a good pick? I'm thinking about Micheal Mitchell, Donte Whitner and Bruce Irvin in particular. It's not like either of them have turned into Ed Reed, but Mitchell wasn't expected to get drafted when the Raiders took him in the 2nd round, and Whitner was a borderline first round pick when the Bills took him 8th overall. Irvin was considered a mid-2nd round talent, but went 15th overall. 

Are there other guys who were considered big draft reaches at the time but have worked out?
