Comment: Should the Rangers advance to the 2014 Eastern Conference Final, the 2014 second-rounder would become a first-round pick. In the event Callahan should re-sign with the Lightning, the Rangers would receive Tampa Bay`s second-round pick at the 2015 NHL Draft while the Lightning would receive the Rangers` seventh-round draft pick in 2015.
