It's a difficult task but someone's got to do it !
We have just ranked the top 20 skaters and top 5 goalies from the OHL available for the first time for the 2012 NHL Entry Draft. Obviously, things change from month to month, and other than probably Nail Yakupov at number 1, you could probably change the order of the next 19 almost any way you want and can't be that far off.
Personally, having attended 32 OHL games to date, and many others on PVR, This list is the way I see it as of the end of November.
