I Understand Greene has been playing at a high level lately, but I would not put him in your starting lineup this weekend. During the Patriots game, Greene left with a concussion. Although he returned, who knows how effective he will be with it this weekend. Greene really struggled against the Dolphins in week three. He carried the ball 19 times and only had 40 yards, an average of 2.1 yards a carry.
Second year receiver, Jeremy Kerley, had a career year last week. He caught eight passes for 120 yards. Right now he is Mark's favorite target and should see a lot of passes going his way on Sunday. He can line up in the slot, go deep, or even help you with a good punt return. At the Flex position I would 100% start Jeremy Kerley.
Dustin Keller has missed most of the season so far, but he finally returned to his old self against the Patriots. He caught seven passes for 93 yards and a touchdown. He made some clutch catches and looks like a good waiver pickup in Fantasy. When he is healthy, Dustin Keller is a very good fantasy tight end. I would expect at least five catches this weekend.
