Braydon Coburn's muscular play was conspicuous during the Flyers' 2-1 win over the Rangers in Game 4 of their opening-round playoff series Friday night. He played 25:27 grueling minutes against Rangers superstar Rick Nash and shut him down. Nash played 17:11 with five shots and was a minus-1. ''I thought (Coburn) had a great game," Flyers coach Craig Berube said. "He skated, really skated and was strong on the puck and strong on his breakout plays. He did a great job down low against Nash. That is not an easy guy to check. That whole line is not easy to check with (Marty) St. Louis and (Derek) Stepan, a good line. Our D as a whole did a good job."
