I wish there was a stronger word than weird. Sometimes he scores, sometimes they randomly replace him and run a dive for a td, and then if he runs and gets stopped, its a guaranteed throw to someone else. Can drive you mad.
Obviously their goal is to score points, not get Ridley fantasy TDs.
With 6 different options in the passing game and 3 other RBs who get carries, I'd say 8 rushing TDs is pretty damn good and way better than anyone who drafted Ridley had hoped for. Even so, he usually gets a goal line chance regardless. He has even been stuffed a few times only to have the Pats try something else the next play.
