49ers probably have one of the most unique boards of any team in the NFL. That is a positive and a negative. They miss on guys because they take them off for various reasons (medicals, off the field issues, lack of scheme fit, lack of culture fit etc) but they also hit on guys no one else does because they are confident in their culture/scheme/process that they can get the best out of them.

They had a 3rd round draft grade on Purdy but didn't need to take him until the last pick in the draft because they didn't think they needed a QB at the time and no one else had him on their board.
