Russell Wilson conceded his inaugural season with the Denver Broncos has not been what he hoped for, though he made it clear that the necessary team improvements start with himself.

The quarterback threw three interceptions as the Los Angeles Rams ran out 51-14 victors on Christmas Day, leaving the Broncos 4-11 this year – the joint-third worst record across the NFL.

Wilson has struggled to perform following his mega trade from the Seattle Seahawks, with a pass completion of 60.1 per cent standing as the lowest-ever mark of his career.

Meanwhile, he has thrown a touchdown in just 2.9 per cent of his throws – again the worst record of his career.

Though the 34-year-old is not the only player to have disappointed this season, Wilson has vowed to "keep fighting" and remains confident of better displays in future campaigns.

"A lot needs to happen. I have to play to the standards that I know how to play to," he said, via Mike Klis of KUSA. "And I've been playing to my whole career. I'll never let a moment like tonight define me.

"We're at a low moment right now. I don't fear low moments because I know every time, I've always come out the other side. All I know how to do is keep fighting, keep battling.

"The reality is, it's been a storm. It's been a storm all year. It's not what we hoped for, not what we dreamed for. But it doesn't mean it's going to end that way for years to come. We got to change it, and it starts with me."

The Broncos travel to face the Kansas City Chiefs on Sunday, before concluding their season at home to the Los Angeles Chargers.
