Sweden's defeat, their seventh out of nine games, meant they finished the round-robin stage in ninth place. Edin, playing in his fifth Games, failed to qualify for the semi-finals for the first time.
It was a crushing campaign for the Swedes, who have enjoyed immense success in international competitions in the past, winning three Olympic medals - one of every colour - as well as seven world titles and eight European titles.
"It was kind of like Murphy's Law for us this week. Pretty much everything that could go wrong, went wrong. We just got into the tournament wrong," Edin said.
"We faced a couple of opponents this week that just outplayed us. I think the other seven games that we played, we definitely had a chance. I have to go back and reflect on what happened."
Double-touch drama
Sweden's campaign was also overshadowed by controversy after they accused Canada of cheating by double touching stones during a game last week, sparking a storm that Edin would rather have avoided.
"Then obviously what happened in the game against Canada took a lot of focus off, there were a lot of negative comments here and there," the 40-year-old said.
"We didn't really expect that to happen. We just meant to do a friendly comment like, 'just let go of the rock'. But obviously that took a really strange turn and turned half of the curling world against us. It's been tough for sure.
"We wish we could start over and do it again and would have let things kind of unfold differently, I hope."
Swedes finish with 2-7 record
In the 10-team round robin, Sweden could only manage two wins and seven defeats from their nine matches, resulting in a ninth-place finish, above only China.
Hopes were high of a strong finish after yesterday's win over the Chinese, while the Czechs had an identical record to Sweden.
However, Sweden conceded double figures for the first time in the competition, as Czech Republic built a healthy 5-1 lead after four ends, and after taking two more in the seventh to go 7-4 ahead, a failed promotion take-out from Oskar Eriksson allowed the Czechs to steal three more.
Sweden called it quits after eight ends, ending their Olympic campaign with a 10-4 defeat.
Edin did not play the entire game against the Czechs, allowing alternate Simon Olofsson to come on.
"I didn't play well at all. So there was no reason to keep dragging the team down," Edin said.
"But it was more so for Simon, who is doing a really fantastic job outside the games, he's here every evening practising. It's fun for him to play a couple of shots at the end of the game, even though the situation he gets in is tough.
"The rest of us have been here before. We're maybe not enjoying it as much in our fifth event. We've been super, super bad. But for him, it's the first Olympics and it means the world to him."
