The aggressiveness that characterized the turnaround for the Detroit Lions under coach Dan Campbell backfired at the worst possible time.

Detroit failed on two fourth-down tries in field-goal range in the second half, contributing to a blown 17-point halftime lead and a 34-31 loss to the San Francisco 49ers in the NFC championship game Sunday.

“It’s easy in hindsight and I get it,” coach Dan Campbell said. “I get that. But I don’t regret those decisions. And that’s hard. It’s hard because we didn’t come through. It wasn’t able to work out. But I don’t. I don’t. And I understand the scrutiny I’ll get. That’s part of the gig, man.
