Compensation for Failure to Sign High Draft Picks
Teams that fail to sign a first or second round pick will be compensated by
receiving a virtually identical pick (plus one) in the following year's draft
(ex., a team that fails to sign the No. 5 pick in 2006 receives the No. 6
pick in 2007). A team that fails to sign a second round pick gets virtually
the identical pick the following season regardless of the round (for example,
if Boston fails to sign pick #62, it will receive pick #62A (~63) in the next
year's draft, regardless of whether pick #62A falls in the supplemental
round, the second round, or the third round). A team that fails to sign a
third-round pick receives a sandwich pick between the third and fourth
rounds. None of these picks may be forfeited. Additionally, these
compensation picks cannot be parlayed into compensation picks in a later
draft. If a player selected as compensation for failure to sign a previous
year's draftee also goes unsigned, the team does not have a right to
compensation for the unsigned player.
