It's that time of year where every sports publication puts out their rankings for various things. With the Raiders being the popular punching bag this year, they tend not to fare well in such ratings.

This time it was NFL.com's Greg Rosenthal who rated the worst position groups on offense in the NFL and the Raiders wide receivers topped the rankings as his worst rated unit in the NFL. Here is what he had to say:

Denarius Moore can be a special player, but he's so rarely 100 percent when he's on the field. He shouldn't be a No. 1 receiver at this stage of his career. The Raiders will let second-year pros Rod Streater and Juron Criner battle behind Moore, with the hope the Jacoby Ford still has something to give. This group actually is better than it was a few years ago in Oakland. There is some promise, but very little production.

It is no secret the Raiders have no proven number one starter. Even when they had Darrius Heyward-Bey, that statement was true. When your quarterback throws for over 4000 yards and the tight end is the number one receiver, there's a real problem with the wide receiving corps.

There are some unknowns with this group and it is possible one of them could step up and prove themselves worthy of the number one receiver. But there are no guarantees that will happen and since the team neglected the position in free agency and in the upper part of the draft, there remain serious doubts about how productive this unit will be.

Also making Rosenthal's list among the worst position groups were the Raiders' tight ends and quarterbacks who were named "Honorable Mention" (which tells me Rosenthal doesn't know what the word "honorable" means). Heck, it's a rebuilding team, and like Rotoworld when they said the Raiders had the worst starting unit in the league, it's easy to point to the team in a state of flux and uncertainty.
