The real experts on draft picks are the guys making the decisions, they know most about the existing roster and have looked in detail at potential propects. The media guys at best know what is publicly available about the existing roster and have looked at all the draft class to an equal amount. I always think draft grades are the like freshmen marking a final degree paper.
I remember us getting a D in 2011, but at the time noone knew that Sherman and KJ were going to be huge but the real beauty is this from 2012:
"After one of the worst picks in the first round I can ever remember, the Seattle Seahawks didn't draft any positions of need or draft for the future.
Pete Carroll is proving why he didn’t make it in the
NFL the first time. Not only was Bruce Irvin a reach at No. 15, the Seahawks proved they were oblivious to their madness by celebrating their selection.
As if the day wasn’t bad enough, Seattle selecting Russell Wilson, a QB that doesn’t fit their offense at all, was by far the worst move of the draft. With the two worst moves of the draft, Seattle is the only team that received an F on draft day."
