Changes made in the next CBA.
A slow/progressive adjusting of offense down (by 0.5R/G) over a prolonged period of time, per the statistical page, HBD is running at 2007 levels for R/G and OPS, since 2007(-2011) rates have fallen by nearly 1R/G.
Non uniform + unusual development cycles for players (makes adv worthwhile, with a generic development profile it isn't), could include, false plateaus, false peaks, multiple peaks and drops.
Less accurate draft/int'l scouting or at least on a different rating scale to that of the advanced scouting, so the two aren't directly comparable.
Occassional player characteristics changing, i.e. low control players developing control as they age.
