Wouldn't say it was a bad call at all. As you said, SF covered for pretty much the entire game, they basically outplayed Seattle for most of it, and had a couple of unlucky items go against them. Most importantly, if not for a fluke deep 4th-and-8 touchdown to a receiver who barely does anything, and wasn't even known until a handful of weeks ago, the 49ers are still in control of this game and are in good position to add to their lead... yes, there was offsides on that 4th-and-8 anyway, but San Francisco easily could have contained them on the should-have-been 4th-and-3, and even if they don't, Seattle's lackluster-up-to-that-point offense still had to go another 20 or 30 yards into the endzone, which at that very point, seemed highly unlikely.
No need to apologize or say it was a bad call. You have a good track record with these and even though it didn't produce a victory, it was not a bad call AT ALL. Nobody made a bad call with this game; it's just one of those matchups that is one play from going the other way. And when a game like this is so intensely-fought and is one play from going in the other direction, nobody involved made a bad call at all.
