Yes the Blues love him that is why they continue to bring him back. Great leader and always produces and somehow manages to keep the puck on his stick.
Current roster is at or very near the salary cap limit, and the team seems to work very well together. I wouldn't bring anyone back if it upset the chemistry. My choice, however, would be Bellmare, for faceoffs and overall defensive play. I liked Perron, but we have plenty of scoring forwards, most of whom are good two way players. Faceoffs are important and we could use a faceoff stud.
