I can see what you're trying to get at yoda and to a certain extent i agree. Certainly there can be great tactical minds in divisions other than the ABBL but you can also get by with just having 1 or 2 major strengths whereas if you've gotten to the ABBL and stayed there it becomes more about having a complete team and using your entire team.
That said, i don't think it's absolutely essential that the NT manager needs to be in the ABBL. As long as you're active on the offsite forum then you can learn the players and makeup of the team. Hopefully the tactics discussions i set each week will start getting some replies and interest as people start to look towards taking over the team.
