SEATTLE — Losing here is an annual routine for the 49ers, and Sunday’s eighth straight losing visit came with all the familiar trappings en route to a 43-16 defeat.
Their offense couldn’t produce nearly enough points, not even with a 414-yard outburst from Nick Mullens.
Their defense couldn’t get out of their own way, whether it was bungling pass coverages or committing penalties to make Richard Sherman’s Seattle return moot.
Their special teams also chipped in with blunders, from muffing a punt return to allowing an 84-yard kickoff return right after halftime.
Even coach Kyle Shanahan drew an unsportsmanlike-conduct penalty — and one more would have gotten him mercifully ejected.
