NHL Undrafted Elite

Sergei Bobrovsky
Despite the Philadelphia Flyers considering drafting Sergei Bobrovsky in the 2006 NHL Entry Draft, it never happened. Due to the difficulty of signing Russian players at the time. In May of 2010, Philadelphia decided to go for it, signing Bobrovsky to a three-year, entry-level contract.
