Derrick Williams was the number 1 ranked player in high school and he was drafted in the 3rd round. Athletes develop as they go from 17 to 22 years of age. How a kid played when he was 17 is virtually irrelevant.
The only situation where it may make some difference is a player that has virtually zero college experience (Matt Cassel).
A player like Harrell and Daniels have hours upon hours of tape on them. The scouts pour through those tapes and apparently were not very impressed. It doesn't mean that these can never be good NFL QBs, but the odds are stacked against them. Even Matt Cassel was drafted.
