Eric "concussion" Lindros. He had all the potential in the world but couldn't seem to string together a full season. He played for Toronto in his last season and started as the best player on the team, but unfortunately he fell victim to the concussion again. 2010 was a great run for the Flyers, they seemed to come out of nowhere. Similar to St Louis in the MLB last year. They've lost many of the stars that they had from that run, but have somehow maintained their position as one of the top teams in the league. Very impressive management, really.
