Where the heck else would they play? They are an all-04 team and a “pure” 04 team would not voluntarily play up against the best 03’s that you find a AA. You would want to stay where your age predominately is which is national A. The skill level is the same in both divisions it’s just that AA is mostly 03’s and A is mostly 04 so obviously if they competed against each other, kids a year older at 03 should roll teams that are all 04. Not to mention why would an all 03 team want to play against kids a year younger than them anyway The kids of lesser ability play in American A or the B division. The DVHL itself will tell you the same thing Or maybe you think the Blazers pure 04 team should play up two birth years and voluntarily go into midget 18UA? What exactly is your hard-on for the Blazers 04? Did your son’s team have a heartbreaking loss to the Blazers last year or something?
