Kyle Shanahan has no regrets about his offensive play calls in the Super Bowl last Sunday.

The San Francisco 49ers led the Kansas City Chiefs by 10 points in the fourth quarter, but went on to lose.

"I personally thought we had the best team in the NFL this year," Shanahan said. "And we weren't, and we've got to deal with that. But I'm sure we believe we had that and we should have proved that and we didn't get that done. And that's what's really cool about sports, that's what hurts about sports, that's what's fun about sports. It's why I love sports and it's also why everyone likes watching it, because there is a lot of emotion in there and when I do feel this way and stuff, I mean it, it makes me feel stronger because it does hurt a lot. But I also know how much I can deal with it. And if that's the worst stuff that happens, I can't wait to try our butts off to get back there next year."
