I disagree with all of this kw niche stuff.
Kw has remained a starter because they haven't gotten anyone better.
When kubiak first got here he went out and got Eric moulds to be the #2 wr. Ther is no blocking wr role on this team. That's pure fan myth. Again, the reason kw is still a starter is because they simply have not had anyone to challenge him for the spot. They have made due with the best they had to offer.
If these rookies step up I would not be shocked if kw is not on the team next year.
If a receiver emerges as a real threat in the passing game on a consistent basis, expect to see kw's snaps dwindled.
