The author didn't really say his opinion on who could emerge in that spot, but did say Carter and Harper can be placed on the practice squad while Dobson and Martin cannot. The author did say Carter is in the Edelman/Amendola mold which could provide some insurance since both are currently hurt.
HOU WR Nate Washington - Week 18, 2015 Fantasy Football Outlook
Week 18 vs. Kansas City
In the win over the Jaguars last week, Nate Washington had just a six-yard reception before departing with a hip injury. During the final four contests of the regular season, he totaled only eight grabs and one TD. Despite registering six catches for a team-high 105 yards in the Week 1 loss to the Chiefs, Washington should not be a part of your post-season fantasy roster.
