While the release of Trey Sermon is both surprising and disappointing, don’t get it twisted - the 49ers are still very good at drafting players.
To be clear, every team misses on certain picks, and every team misses on high draft picks. Without question, the entire exercise is more of an art than a science. The 49ers, however, continuously get value deeper into the draft than many teams around the league.
Players picked in the first three rounds usually come from big programs that are full of highly ranked high school recruits. So, most of the time, there is more information available on them than all the other guys in the draft.
