Oiler fans may (HA!) recall that Curtis Glencross was lost as a Group 6 unrestricted free agent a couple of years ago. The rule for Group 6 free agency in the CBA is as follows:
"Any player who is age 25 or older who has completed three or more professional seasons, whose SPC has expired and: (i) in the case of a player other than a goaltender, has played less than 80 NHL games... Any Group 6 player shall, at the expiration of his SPC, become an unrestricted free agent..."
Ryan Stone turned 25 on March 20th of this year, has played in 5 professional seasons and only 35 career NHL games. Now, in at least one part of the CBA, "age" refers to age on September 15th (article 12.1.c) so it's possible that he's still a restricted free agent who counts as a "24-year old player" based on his age last September 15th. But, he is after all 25 right now. I checked up on nhlnumbers.com and they have Stone listed as a pending UFA, whereas capgeek.com still has him as a pending RFA. I'm not totally sure of the correct interpretation but my guess is that he's an unrestricted free agent as of July 1st. If he's an RFA this season, Stone will need to play in at least 45 games next season, or he'll become an unrestricted free agent.
