Much has been said and written the past few days about rookie Tyler Seguin's impending first date with the Stanley Cup playoffs.

But as he continues to work out with the Bruins' third line in preparation for Game 1 of the Eastern Conference finals against the Tampa Bay Lightning tomorrow night at the Garden, it doesn't hurt to get advice from a guy who has participated in many a postseason game over the years.

Mark Recchi, who made his Stanley Cup playoff debut 20 years ago as a member of the Pittsburgh Penguins, put it this way: "Just make sure you're ready. And do a smart thing — get in there, maybe get bumped, go get a bump, get yourself physically involved in the game and emotionally involved, and you'll be fine.

"Once those first couple of shifts are over," said Recchi, "he'll realize what it is and he'll be ready to roll."

Seguin, a 19-year-old rookie, will suit up as a replacement for Patrice Bergeron, who suffered a concussion in the Game 4 clincher against the Philadelphia Flyers last week in the conference semifinals. While Chris Kelly will move up to the second line to replace Bergeron, Seguin will be at right wing on the third line with Michael Ryder and Rich Peverley.
