I seem to remember a topic many moons ago regarding this, but a search reported nothing...
It seems there have been occasions where players have been given an inappropriate SA when they have been generated for the Scouts list or Recommended players.
One I got this morning is a case in point. A DC does not have Crossing as a White skill, so how can the Corner Kick SA be helpful in this case?
...and in the Scouts list, a litter of players with SAs that don't match their white skills. DC with Free kick? DMC/DC with Penalty taker?
Some of the combinations in the transfer market are mind-boggling as well. Makes those players impossible to use and reduces the choice you get.
