Here's who we lost from the Checkers and what they are doing now:
Poturalski: 25 years old, and has played 6 games this year with the AHL San Diego Gulls
Saarela: 22 years old, traded to Chicago, promptly sent down to the AHL. Then traded to Florida, promptly sent down to the AHL. Got 3 games in the NHL, did nothing and is back in the AHL
Necas: 20 years old, playing in the NHL on the Canes
Carrick: 25 years old, playing in the AHL for the San Jose Barracuda.
Gauthier: 22 years old, currently going between the Canes and Checkers
Shilkey: 25 years old, currently in the AHL with the Bridgeport Sound Tigers
Roy: 22 years old, traded to LV, got a 7 game look on the 4th line when injuries hit, currently in the AHL with the Chicago Wolves
Brown: 27 years old, currently in the AHL with the Chicago Wolves
Renouf: 25 years old, currently in the AHL with the Colorado Eagles
Jurco: 26 years old, signed by Edmonton, but after doing nothing in 12 games was sent down to the AHL and is playing for the Bakersfield Condors.
Nastasiuk: 24 years old, currently playing in the AHL with the San Antonio Rampage
Robertson: 28 years old, currently playing in Austria.
Fleury: 23 years old, currently playing in the NHL with the Canes
Didier: 26 years old, currently playing in the AHL with the Providence Bruins
Tokarski (Goalie): 30 years old, currently playing in the AHL with W-B/Scranton Penguins
So of the guys "lost" the only ones that could even be considered prospects (22 and under) are Saarla, Necas, Gauthier and Roy. Two of those are with the Canes and two are in the AHL.
NOTE: I left out guys like McKegg and Maenalanen since they spent the end of the season and playoffs with the Canes, but they aren't prospects.
