2009s who may be overrated due to birthdate

The cutoff date for each draft class is Sept. 15 -- you must be 18 by this date in a given draft year to be eligible. Players born in late September and October have an advantage of being almost a full year older than some of their cohort. They are naturally further ahead in development and are often unintentionally overrated.

Here's a list of early birthdates for 2009, the potentially overrated in the 2009 draft class:
John Tavares 9/20/1990. Yes, that John Tavares.
Stepan Novotny 9/21/1990
Gabriel Bourque 9/23/1990
Dan DeLisle 9/24/1990
Jordan Schroeder 9/29/1990
Alex Chiasson 10/1/1990
Mike Lee 10/5/1990
Nazem Kadri 10/6/1990
David Rundblad 10/8/1990
Seth Helgeson 10/8/1990
