Slim,
Those other pieces (i.e. AD awards, Gen endorsements, etc) make perfect sense for the AD whole-person concept.
However, ROTC also tries to select via the whole-person concept. They just use different variables. The PCSM score is only 15% of the entire pie. The rest are: PFT score, Field Training ranking, GPA, and the big one - RSS (a.k.a. Commander's Ranking and/or class ranking) is 50% of the overall score.
ROTC does their best to encompass everything that someone does during their ROTC career to get all of an individual's strong and weak points/performances. However, it's just that, all they have to go off of is ROTC. However, you'd hope that they can get a good idea of someone's potential as an officer after training and evaluating them for ~4 years...at least enough to be accurate the high-majority of the time.
