I have never seen Vincent Lecavalier walk this way, so if you want his you'll have to try something else. The visiting team is really hit and miss. If they all ride the bus, they'll either all walk where you can call for them or they will all walk the back way and you cannot get a single one. Visiting teams are tougher to get, but some players will sign for you. I have seen some players walk right by like they did not even hear you, while others will sign for everybody.
Goalies are the toughest to get before a game, especially the starting goalie.
After the game you can wait around the same spot, or around where the players drive out and try to flag them down. I have not tried this very often, but I have heard of many successes. You can hear the views of the radio guy, some call-ins, and an interview with a player. After the show, the player will sign for everybody. They are always nice and I have even gotten a few pictures taken with them.
