England's season of progress came to a juddering halt at Lansdowne Road on Saturday as Ireland wrecked their hopes of a Six Nations grand slam with a 24-8 victory that was more emphatic than the scoreline suggests.
Johnson later admitted his team had been outplayed by a better, smarter Irish side but said the loss could be a useful marker in his team's development heading into this year's World Cup and beyond.
England grabbed consolation later Saturday when France's victory over Wales in Paris ensured that Johnson's side finished the season as Six Nations champions, their first title since 2003.
"We said at the start of the tournament it was going to take a heck of a team to win five this year -- but we had a shot," Johnson said.
"There's a scar there now and we've got to wear that scar a little bit. We can make that a good thing or a bad thing from where we go from here.
"Do you have to get your scars and bruises in before you go and win something? You hope not, but probably you do. Ireland had theirs before they won their grand slam and I certainly had mine before I won ours in 2003.
"We're devastated at losing. We've never gone down the the easy route of saying 'Oh well, we're learning and we're young'. We came here to win and we we weren't good enough on the day.
"I said to them after the game 'Let's take this on the chin; we've got no-one to blame but ourselves.' Ireland played very well and we got beaten."
"All in all we've got no complaints. We got what we deserved. We're just disappointed that we didn't make a better game of it."
