NE's pass coverage is horrible. Nelson is gonna be a stud now with Johnson iffy and Parrish done for year. I'd roll with him all day long. Other options aren't bad either, but the Raiders WR situation is a little fluid right now. Moore had a big week, but OAK was also missing 3 WRs a week so it's hard to tell what PT will be like when those guys return. I'd keep Moore reserved for now. I also like Decker in the thin DEN WR group, but I like Nelson more. With McGahee, it's hard to tell. Fox will likely ride Willis' hot hand even if Moreno returns this week, but I don't see him producing another 100 yd game again.
If nothing else, NE will probably get the lead up to at least 2 TDs on BUF as they usually do. That means more passing by Fitzpatrick and more opportunities for Nelson. I'd roll with him.
