Having elite talent and needing elite talent are not the same thing.
Oregon did have some elite skill guys. But I don't think their overall team talent was out of line for what we can get here. Their best run was from 2009-2012. Their class recruiting ranks from 2007-2011 were 14, 34, 30, 12 and 12. Average of 20.4. As I've often speculated, recruiting gets more successful after you have good success, not before. Nebraska's over the same time-frame were 19, 24, 40, 26 and 16 for an average of 25.
So it's not at all unreasonable to get to the recruiting level that brought them a ton of success.
