On a nice intermediate or deep pass, the QB may need to thread the needle into an area between the CB and a safety that is converging on the throw. No RAC as the ball gets there before the safety who makes the tackle. I think we can all agree which is the more impressive (accurate) throw.
Another flaw in purely going by YAC, is that all the data is based on completed passes. So within the sample size, there is 100 completion %. Since each qb operates in a different system, it hard to differentiate between them just based on YAC. Kaep doesn't get the amount of screens that a manning does (as you mentioned).
I think YAC is better served in comparing WR on certain concepts. For example, if one WR is averageing 8 yard of YAC on flanker drive and another is averaging 4 yards of YAC on the same concept, then conclusions can be made regarding the way those WRs are running that concept.
