09:30 AM ET 07.20 | Chris Stewart's signing pushes the Blues closer to the NHL's $64.3 million salary cap ceiling for next season. They have approximately $56.1 million committed against the cap, according to Capgeek.com. That leaves the club $8.2 million to re-sign Alex Pietrangelo and Magnus Paajarvi. Jake Allen is also a restricted free agent, but the club may be gearing toward a two-way contract for Allen. The fact that August is approaching and Pietrangelo remains unsigned has some concerned, but Armstrong said Friday that "we are going to do what is necessary to get him signed. Now whether we decide to go short-term based on what Alex wants or long-term based on a mutual desire." It's believed that Pietrangelo's camp is asking for close to $7 million a season, while the Blues may be seeking to play less $6 million or less. Either way, that represents the bulk of the Blues' remaining cap space, leading some to believe another trade is necessary. "No issue," Armstrong insisted. "We have more than enough space to get everyone in the fold."
