Because the officials allow it to often. It needs to be enforced. It is basically the same five teams in our league. I have watched it get enforced more in the league in the last three weeks. Maybe the letter I sent to the league had an impact. I doubt it, not one letter. However, maybe other letters along with comments by on air announcers questioning how easy players go down. One announcer - not sure of the game ((not UND)) talked about the phantom fall receiving a 2-minute by opponent. It might have been a UMD game (by the UMD opponent) since we watch a lot of UMD games.
