    【Question】
    What is the average BMI of an All-star player? average BMI refers to AVG (Multiply(Divide(weight, Multiply(height, height)), 703))

    【Evidence】
    average BMI refers to AVG (Multiply(Divide(weight, Multiply(height, height)), 703))

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT AVG(CAST(T1.weight AS REAL) / (T1.height * T1.height)) FROM players AS T1 INNER JOIN player_allstar AS T2 ON T1.playerID = T2.playerID
