2K gets away with a ton of "ratings-speak" over the years because most people have short memories and don't double-check facts/spreadsheets/etc.

Plain as day that there isn't any difference from last year (if anything the rookies might be even higher than usual).
The only thing 2K said they were adjusting was a few ATTRIBUTE scales (which will naturally lead to some minor OVR variance). It's really their way of saying "we've had screwed up rebound ratings for 10 years and it's about time we finally got around to fixing that" (which is why PF/C ratings have tanked, while perimeter positions have been unscathed - akin to ripping a bandaid off one wound to place it on another).
