I don't know it's a matter of "accepted" as much as it is "we do with what we have until recruitment picks up." In my day, Sun routinely put out around 40 horns. Sometime a few less - sometimes more. This year they only put 14-15 on the field, but this years iteration is basically an entirely new corps after being off the field last year (after the Class A win in 07), and relocating the corps back to Long Island. New ballgame, new recruitment efforts, new everything. Starting from scratch.
Would they - and we of the alumni - have liked to see a larger horn line? Of course - who wouldn't - but "we do .... etc." All things considered, I think they acquitted themselves well.
