It kinda is, actually. The evaluators ask the coaches, they don't take them all- but this is akin to nominations from coaches.
Asking a coach, or requesting information is much different from nomination. If you believe this is true, then the Blues w/ 2 teams in the top flight only had 4 girls selected, so are we to believe that Rennie doesn't care about accolades, winning or player recognition? Are there some coaches that push for this, of course, but that is the exception and not the rule.
At the State Cup games there were evaluators sitting, observing and taking notes. picking players is an inexact science, so with such limited exposure, expect a lot of good kids getting passed over and a lot of 'average' kids being selected. Subjective analysis from one watching 2-3 halves of play over a weekend. If your kid gets selected, celebrate their recognition for playing well with critical eyes on them. If they didn't, oh well, not the end of the world.
