UA Senior All American selections have never been about High School Play. It is all based of the Club Summer circuit and in recent years since the "Underclass Games" and even The Committed Academy. They start announcing the players in the beginning of April so they already know how is making the team (well before HS season is complete). The main person who evaluates players is the same person who takes point on the IL Player rankings (there is always a very strong correlation between IL Senior rankings and Under Armour AA selections). All of the evaluations are done in the summer at the major tournaments and at the IL underclass games where players can be seen competing against the best players from around the country. Go back and check, If a player is ranked in the Top 40 by IL there is a very good chance they will be selected as an UA AA.
