i agree with the coach's decision on this matter. if i were Jason, (the player) i would want my goals to be important goals. there is a major difference in scoring 43 goals (example) in a season against really poor teams, and 43 against quality opposition. jason and his dad both know that he could have achieved this honor, but this instance certainly shows the maturity of both father and son.
also, there comes a time in an athlete's career when honor and integrity become more important than statitics.
