San Francisco 49ers head coach Kyle Shanahan acknowledged going through a "grieving" process after the Atlanta Falcons' Super Bowl collapse.
The former Falcons offensive coordinator defended his much-criticised play-calling during Atlanta's second-half Super Bowl LI collapse against the New England Patriots.
But Shanahan said it has not been easy to move on from the 34-28 overtime defeat.
"We played that game how we played the entire year. I called plays the way I did the entire year," Shanahan said at a news conference on Thursday.
"You live with the consequences."
It certainly will take time for Shanahan to escape the shadow of that setback even as he embarks on his first head coaching job on the other side of the country.
Shanahan thanked his new boss, 49ers owner Jed York, for giving him an extra day or so of recovery time after Sunday's loss in Houston before he reported for duty in San Francisco.
The loss was "as hard as anything I've gone through," Shanahan said. "Jed told me to take my time. I was definitely grieving and probably will for a while."
Whatever lingering regrets Shanahan might have will soon be pushed aside by the considerable task of teaming with new general manager John Lynch in an effort to get the 49ers back on track following a 2-14 season.
