I not creating the teams via teambuilder. I'm only using teambuilder as a reference. I have a spreadsheet going for the Big East right now where I am adding in freshmen(created players) and fixing any other mistakes.
I'll still have to make all the changes in game, but I'm at least getting the research and development...haha...work done ahead of time, so that when I do have the game, I just have to plug away into the game's rosters.
Not the best of solutions, but at this time, its the only thing I've come up with to try and lessen the burden of creating accurate rosters once the game drops.
