St. Louis Blues GM Dough Armstrong doesn't expect Alex Pietrangelo or Chris Stewart to be re-signed by the time free agency opens Friday. Both players will be restricted free agents after the team tendered them by Tuesday's deadline. The Blues are playing with fire a bit here as each player appears to be a candidate for a rival offer sheet, particularly Pietrangelo. Although he took a step back in 2013, Pietrangelo remains one of the better young defensemen in the game. Stay tuned.
