AMC: ball-winner centre?
Another football nonsense.
That should be for DMCs.
AMC: well-rounded midfielder?
In that case, it should be DMC/MC or MC/AMC or DMC/MC/AMC.
Even 'the professor' is wrong. That should be for a DMC/MC playmaker.
It is clear that the terms used are not appropriate for the positions here. Flaw?
