Like who? Their youth are by and large shit.
They have more players under 23 than Geelong, and more highly rated players in that age bracket than does Geelong.
They have 6 players aged under 23 who were taken with picks below 30 (JOM, O'Rourke, Burton, Lovell, Hartung, O'Brien) compared to the three Geelong has (Cockatoo, Thurlow, Lang).
The Hawks have three taken between 30 and 50 (Howe, Hardwick, Miles). Geelong has two, both in the 40s (Kolo, Gregson).
Hawthorn has three players taken at 50+ (Pittonet, Sicily, Brand). Geelong has five (Cunico, Gardner, Buzza, Hayball, Bews).
The Hawks have more top-level young talent than Geelong, with guys like JOM and O'Rourke. Geelong has fewer players in this age bracket and a much larger proportion were taken in later rounds.
