Do you actually have players who plays 48 minutes in 2 league games a week?
That said, in terms of the "familiar with star players and not being afraid they are sold", I wonder if it's largely affected by activities on the transfer market. I see in your last 3 trades, you had two pretty high profile ones, including a 200k salary player who's now retired and a player who went for 2m. I reckon that played a part as well, especially when you seem pretty active in the market.
