Good list. I could see valid points for any order. Many of their QBs are up in the air and Kirk may be on the most solid ground there. If gun to head:
Kenny Golladay. Seems like the one most capable of being a WR1. This is assuming Stafford continues to QB the Lions.
Chris Godwin. Great player but gets the benefit of having Big Mike take the top corners. QB a concern going forward but is a good security blanket for a young signal caller.
DJ Moore. Love him as a player, just not sure he will ever get fed WR1 target amounts. (Edit...he has 10 and 11 targets last two games). Also unsure what the QB situation is going forward.
Christian Kirk. Love the pairing with Murray and showed his upside last week. I just don’t have a good feel for what he is yet. Doesn’t feel like a WR1 but definitely has his place.
DJ Chark. Has had some great weeks and some quiet weeks. New to the production scene so may have caught some defenses by surprise. Least confident based on his short resume.
