Not much to say beyond Foles being reunited with Frank Reich. He would be a useful QB2 in Superflex/Two-QB leagues should Matt Ryan go down. Foles' arrival also zaps any value Sam Ehlinger had in Dynasty formats.
IND QB Sam Ehlinger - Week 17 Fantasy Football Outlook
Week 17 vs. Las Vegas Raiders
Sam Ehlinger looks in line to get his first career start this week against a Raiders defense that ranks 26th in aFPA to opposing quarterbacks. While it’s a nice matchup, the Colts will likely try to win the game on defense and by using Jonathan Taylor, making Ehlinger a very risky fantasy option. Look elsewhere.
Update: Wentz was taken off the COVID list on Saturday and looks like he's going to start. Hopefully this doesn't affect your fantasy plans, as Ehlinger wasn't an enticing option anyway.
