If it is not a keeper league then yes drop DJ.
Morris/McFadden question will be the question of the year. Truth of the matter no one really knows.
I lean towards McFadden. He is better at receiving and is more like zeke with his running style than Morris. The only unknown is actually Rod Smith. He might end up getting more work than the both of them if he shows he is a solid rookie. It is has been the year of the rookies so only time will tell.
