If anyone is wanting to do 25 man rosters so lineups aren't jacked, but want the injured guys to be on the team. Just move them onto the 25 and move a guy down. Shouldn't take too long to do. I'll probably go that route.
I don't believe you need budgets off. I think I read they did make some contract changes, but some they left alone because it would cause trouble with the budgets, so you should be good to go with budgets on.
