I understand the importance and differentials between the two, but have they always been so strict?
I see so many people talk about how stupid some people are suggesting RCB’s to play LCB and vice versa, but I can’t remember previous generations being so limited, though perhaps that’s due to the lesser responsibility on ball playing duties?
It has become more important because of how often teams play out the back. But if a club’s best CBs are all right footed they will make due.
