49ers (0-4) at Colts (1-3)

TV: Sunday, 1, Fox (Thom Brennaman, Chris Spielman, Peter Schrager)

The matchup: The 49ers are still losing, but they’re close to being legitimate. Their last three losses have all come by three or fewer points. Their run defense has also shown some pretty good signs, led by a young defensive line made up of three first-round draft picks. There’s a lot to like about what new coach Kyle Shanahan has done, except the lack of a win. The Colts are 0-3 vs. NFC West teams this season in being outscored 108-40. But the 49ers have lost six in a row vs. AFC teams. Colts QB Jacoby Brissett was starting to resemble a legitimate NFL starter, but the leg injury suffered vs. Seattle could affect his performance. Luck is at least another week away.
