Overdraft. Reach. Whatever word you want to use for it, every year there are players taken a little too high in the NFL draft.
Most of the time, a reach occurs when a team is attracted to a player's physical tools, ignoring his on-field production. The Raiders made a habit in the late Al Davis years of drafting players with fast 40-yard dash times, regardless at times of whether they were successful college players.
In other cases, a reach will simply be a case of one team valuing a player more than other teams—or at least, more than the public perception of the value of these players.
Therein lies one sticking point in such a list as the one I'm about to embark on: Ultimately, it's based on perceived draft slotting, with no knowledge of some of the most important aspects of such determinations (such as private meetings and medical records).
Character concerns, injury history, one-year-wonder status and other factors are sure to be cause for hindsight three years down the road.
