You can do just as much in D5. First of all, in D5, you can build up your arena to 7-10k, so you can be ready from teh get go when you promote or stay down, and handle better players while being able to afford. Secondly,training players out of position in D5 isn'ta big deal. There is about 10 bots in each D5 league (I think). And about 90% of bots don';t even have strong inside players at C/PF, or strong guards at PG/SG/SF positions. So you can still be competive, build up your arena, and tank to train players and gain money to buy players when you think your ready to promote and are done training that player. You can still test out your tactics. I'm just saying that in D5, it's easier to train, learn teh game on BB. I was in D5 for a while and built up my arena and trained players
