Sure, I know some of these terms are an overkill! Well, XG actually makes me really puzzled, they just count how many great opportunities a team created. Low block is just a defensive startegy and yes, Micah does make a lot use of it. ?Second phase? is when play starts emerging from the attack again after it has hit the core of the defense. I did not know that ?Transitions? means what you just said ? when a team loses the ball and the other in a haste attempts to go forward. Inverted full-back? In all fairness, it?s simply a full-back who has transferred into the middle of the park and performs like a midfielder. ?Recycle the ball? which is a phrase often used is simply gaining the ball back and distributing it around. And ?goal involvement?? Actually it refers to any player directly or indirectly involved in an act of creating a goal, not the creator only.
