The good news coming out of Sunday is the 49ers clinched a playoff spot for the first time since 2013. The bad news is that with their loss against the Falcons, the 49ers dropped to the No. 5 seed in the NFC, going from home-field advantage throughout the playoffs with a first-round bye, to a road game in the wild card round.

The 49ers were missing several key pieces on defense and it showed, especially late in the game. Here are the studs and duds from their upset 29-22 loss to Atlanta:

Stud: TE George Kittle

Kittle followed his game-winning play last week with a monster performance. He posted a career-high 13 receptions for 134 yards. The 134 receiving yards accounted for 67 percent of Jimmy Garoppolo’s 200 passing yards. Garoppolo also targeted the tight end on 17 of his 34 throws. Kittle was the largest part of the 49ers’ offense on Sunday, and without him the game would have been nowhere near as close as it was. The 49ers are used to Kittle being an important piece, but he can’t continue as their lone receiving threat if they’re going to make a run in the postseason.
