I am no soccer expert, as I tend to watch every four years and not much in between. But I wondered yesterday while I watched the game whether the two yellow cards equaling one red (meaning the player is kicked out and the team plays with one less player) makes it harder for the referee to call fouls. That is, if a player already has a yellow, does that lead the ref to then avoid calling a second to avoid upsetting the competitive balance of the game?
Is this a problem much of the time or only when a team is more physical than usual? I don't know, but I doubt that I will be watching that much more soccer in the near future.
