With a strong possibility that Brandon Marshall may be leaving, a No. 1 Wide Receiver is still a requirement. This issue will have to be addressed in the draft, a trade, or with a Free Agent signing.
Marshall leaving would put a huge hole in the Denver offense but can be fixed. Gafney proved he can be a great back-up but will not be that go-to guy in every game. He doesn't have Brandon's size, speed or ability to make the YAC.
Royal has also been mentioned as the next #1 if Marshall leaves, but maybe there is another spot for him.
How all this shakes down is yet to be determined. The Receiving situation (other than Marshall's situation) is one of the biggest issues for the Broncos, but hasn't really been discussed much either in the local media or on this site.
