If you enter the game around mid way through the first half, your team scores

Last season I used to support all a guy in my leagues opponents (basically because he done it to me for 5 games before I started doing it to him) He used to come in around the 25 min and his team would score like a minute or 2 later, pretty much every game. Could be coincidental but I reckon I watched it happen around 10 to 15 times.
