In various redraft leagues I've interchanged my late round WR sleepers already. Burleson (hurt by the signing of Branch), Gabriel (I expect inconsistancy) and Porter (issues) got dropped for the likes of other upsiders such as Williamson, Michael Clayton, and Colston. In the case of Colston, it was a Yahoo! league where I discovered he was also eligible as a TE option for me, which was nice since I drafted both Watson and Winslow at great value late, but they have the same bye week. I'm going to shop Watson now I think.
