For hockey card collectors, the 2013-14 releases were supposed to be a boon for rookie cards. The lockout during the previous season resulted in a few of the normal releases being shelved, most notably the second series of the flagship product for Upper Deck. Series 2 is usually a big deal for collectors looking for rookie cards of players that debuted in that season. However, the NHLPA decided that due to the lockout, the only rookies that would appear in licensed sets would have had to make their debut between the 2012 All-Star Game and the 2012 Stanley Cup Finals.
