The Guinness PRO12 winner played every minute of the three-match Lions Series against New Zealand which the tourists drew 1-1.
The final match of the series was a thrilling 15-15 draw with Davies once again having a major impact outside Owen Farrell.
He made a crucial covering tackle on Ngani Laumape in the first half before making a big tackle on Jordie Barrett to earn a turnover for his side.

Despite the award though, Davies was quick to pile credit on the rest of the Lions squad who had their backs to the wall for much of the first half in Auckland.
“I’m very humble, chuffed to bits to get the award, voted by your peers,” he said.
“But you look back and it’s a team effort, with 40-odd players and we dug in and achieved something very special. I’m chuffed to bits.
“I’ve been really happy, I’ve enjoyed my rugby. I played with a smile on my face and it’s great to be a part of a special group of players.
“After the first 20 minutes I felt the worst I’ve ever felt but it was a great comeback to grind out a draw in the end.
“For us as a group we’ve achieved something quite special as well.”

An historic Lions Tour ended all square after the draw but it was still a memorable occasion at Eden Park as the tourists battled back from 12-6 down.
The Lions become only the second squad to come away from New Zealand without losing the series, following the 1971 tourists, and Davies admitted the match could have gone either way.
“It was a very intense start, in the first 20 minutes they came at us out of the blocks and it was credit to us to fight back and grind it out,” he added.
“Some might say it was a fair result, we’re disappointed we didn’t get the win.
“I think we’ve done ourselves proud. It’s been a great Tour.
“We came together and we became a team from four different countries, it was a great achievement for us and I think we can hold our heads high.”
