The first player you showed would be long gone. The 2nd would likely be as well.
Your keeper and ST perform well as you said.
I do not tolerate any player outside of GK who doesn't have better than a 7 avg.
I thought for a while that I couldn't expect that from a CM or wingers but I have since found players at LW/AM/RW/CM who all score better than 20 goals per season and have good avgs. They might have a slight dip in form from time to time. Like my AM has had a half dozen 7's in a row but if they are getting a bunch of 5's/6's they won't stay.
