With American Idol coming to ABC in the spring, likely to go to Sundays, Sunday night needs some placeholders for fall. Since Once Upon a Time is 22 episodes, I expect it to move to Fridays, where the 8:00 hour has recently been opened up. Quantico has a short order for season three, so I expect it to return to its original timeslot for the fall. 10 Days in the Valley is a mini-series, so it makes sense for ABC to air it on Sundays this fall as well. There is one more timeslot open on Sundays, and I think it is between The Gospel of Kevin and The Crossing for that timeslot, as they are the most likely new series to be limited, since they are high-concept. I am placing The Gospel of Kevin in that timeslot because of its comedic nature, making it more compatible with America's Funniest Home Videos, and because I think it will have a more similar audience to Once Upon a Time, who used to be in that timeslot, than The Crossing would. I chose to put The Gospel of Kevin at 8:00 and 10 Days at 9:00 due to those reasons, and because 10 Days will likely have less overlap with The Walking Dead than Kevin would.
When it comes to the comedy hours, I expect 5 of ABC's 7 returning comedies to stay in place. I think that Fresh Off the Boat will have to wait until 2018 to begin its fourth season, and Black-ish will make the move to Tuesday. Modern Family and Black-ish would then be lead-ins to the new comedies in the fall. I expect the Zach Braff project (formerly Start Up) and The Mayor to end up in the fall because they are the most compatible with those two shows, with Start Up going Wednesday and The Mayor going Tuesday for maximum compatibility. I also expect these two to be chosen for fall over Splitting Up Together because I believe that ABC ended up with Splitting Up Together because they wanted Deception (like how they got Fresh Off the Boat because they wanted Cristela and another season of Last Man Standing). Designated Survivor stays put on Wednesdays, as does Agents of SHIELD on Tuesdays, but waiting until November to premiere, with fellow Marvel series The Inhumans airing in the fall. I think Deception will air Mondays at 10:00 because it is the most Castle-like of ABC's new shows, and I believe they really wanted it, though I would be unsurprised if The Good Doctor got this timeslot instead. Thursdays remain familiar with the three biggest series of TGIT.
At mid-season, the Sunday night line-up would most likely turn into American Idol at 8:00 and new drama The Good Doctor at 10:00. On Thursday, Shondaland drama For the People will probably premiere at 10:00, avoiding competition from This Is Us on NBC. The one mid-season drama that remains then is The Crossing. Unless Deception fails, there won't be room for it, so I see it airing in the summer, assuming Deception is successful. I do think that it will get a lot of promotional attention for its summer run, because I believe that ABC cares about the series, I just don't think that they have the room for it in-season. On the comedy side, Fresh Off the Boat will be a priority to get back onto the schedule. If one of the two new fall comedies fails, I expect Boat to take its place. If neither does, Fresh Off the Boat will probably fill in the mid-season gap for Once Upon a Time. While this is a very low-priority timeslot, January sometimes does see some higher than usual viewing levels there, like when Last Man Standing hit a 1.5 this season. If both fall comedies fail, I expect Fresh Off the Boat to air Tuesdays at 9:30, and Splitting Up Together to air Wednesdays at 9:30. Splitting Up Together ends up airing in the summer if this does not end up occurring.
