»Told Blake Wheeler is "processing" right now. The 38 year old veteran is still not signed. I'm not sure if his future holds a contract, PTO, or retirement.» - Murat Ates
Ates notes that Wheeler could still potentially earn a contract or tryout contract, but at 38 years old and coming off another injury last year in the playoffs, retirement is on the table as well. Last season, Wheeler signed a one year contract with the New York Rangers and played 54 games, scoring only 9 goals and 21 points.
Slowing down with age and being plagued with multiple injuries in the last few seasons, it's looking very likely that Wheeler may not be playing next season.
