can a dot that is 240 d/o today play pro next season?
Yes. Remember, team movements are processed at the end of Day 41. At that time teams get moved around (up to the next age group OR down if they requested demotion) and the age ranges for the leagues are reset like so: http://wiki.goallineblitz.com/index.php/Leagues#Minor_Leagues
Minimum age for National Pro will be reset to 201 days old, so a 240-day-old player would
be able to play on a National Pro team.
