As the rest of Rapoport's tweet went on say, there are some things to work out first. Johnson is also the first pick of the San Diego Fleet of the Alliance of American Football, so he will at least temporarily need to get out of that to back up Sanchez.
WAS QB Josh Johnson - Week 17 Fantasy Football Outlook
Week 17 vs. Philadelphia Eagles
Here are the point totals for the Washington offense over the past four games: 13, 16, 16 and 16. With a home match-up, Vegas is being "generous" this week with an implied team total of 17.75 points. With a fourth-string quarterback at the helm, this is not an offense to rely on for fantasy production in Week 17. This is a team that's just trying to stay competitive via its defense and special teams.
