Here's a pretty good review of Wings farm system by Hockey's future magazine:

Hockey's Future: The #1 Online Prospects Magazine (Covering the WHL, QMJHL, AHL, OHL, College, The NHL Entry Draft, and All Junior Hockey)

Quote:

Red Wings Top 10 prospects 1. Jimmy Howard, G 2. Jakub Kindl, D 3. Johan Ryno, RW 4. Jan Mursak, LW 5. Justin Abdelkader, LW 6. Igor Grigorenko, RW 7. Jonathan Ericsson, D 8. Dick Axelsson, LW 9. Kyle Quincey, D 10. Darren Helm, C

A thing to note: Grigorenko is fairly high on that list. Hopefully he can come back close to the form he's displayed before the accident.
