Still real farm teams like in HT just can't exist in BB. In HT it doens't matter if your player plays 180 minutes or 90 minutes, in BB you can't let a 250k player play 2 full games a week in a farm team. There are no decent backups so that player will make 90+ minutes per week, which leads to a massive GS drop. The Farm team needs to log in a lot more often than in HT, and even when he logs in it's tough to keep the farmed player at a decent shape.But ok I indeed kind of underestimated the financial part.
When you have a guy with 250K on your team and start him as backup to a 5K player, the 250K player will still get far and away the most playing time
