The biggest play in the CFL belongs to the guys in the striped jerseys. Pass interference calls are not exciting, yet they move the ball long yards and often into scoring position. A lot of teams are throwing the ball up for grabs and hoping to get the call for pass interference. It seems to be working. Look at the Edmonton game.
The refs need to use more discretion on those plays. First of all, the ball is up for grabs, defensive players have every right to go for the ball. When the defensive player is chasing the play and puts his hand up to take the ball, this should not be a penalty. The interception by Hamilton in the end zone was a prime example. There is always going to be some jockeying for position, and some unintended contact but we are seeing way too many pass interference calls.
There seems to be no consistency in the way interference is called.
