I guess it depends on the area there are no restrictions in our area as long as you play in a percentage of the games during the season. In fact the one organization has a team that plays A level tournament all fall, winter, spring and summer - they split them up between the team for the regular season but they who make up the "allstar/select team". They have blown through districts, sectionals, and states (I think they have played maybe 1 close game and by close I mean winning 7-3).
