My unsolicited two cents:
I am going to just keep building my arena... Only having home drafted guys during this course until I get A diamond in the rough draft pick and have a decent sized arena... Then turning that profit on a weekly in v. Means I'll have some pretty pennies saved up come promoting to d.iv then can make push, expand talent pool of my players, staying American for that mercy bonus, and cut the deadweight. Not having to worry about my arena at all in d.iv, then promoting to d.iii again with same lack of worry over arena, also by now that great draftee I scored should be 20-22 by now consistently trained, so he should be able to fully hold his own.
But that's just my idea
