Well yes and no. If you have Lucky and Ross in the back field, Swift at WR, who covers the FB, usually a LB. Maybe even the MLB. Lucky should win that battle. The defense could be told that the ball is going to LUcky but they still have to cover it....because Lucky can't block and when he's put in as a fullback the defense would be tipped off that he will be getting the ball. A 2 RB set is not what is needed. Putting Cody Glenn in as fullback does make sense, since he can do it all. Glenn is the same height and weight as the Broncos Mike Anderson, who has played fullback previously for them.
