And at 26 years old, the bad news for opponents is that he's still getting better.
Biggar was the youngest player to reach 100 appearances for Ospreys and already has over 1300 PRO12 points in his career.
Such is his importance for club and country that Ospreys and Wales teammate Alun Wyn Jones admitted the man from Morriston is the heartbeat of every side he's in.
"You watch Dan - whether it's with Wales or the Ospreys - and when he's playing well he gets us on the front foot," explained Jones.
"That fulcrum between 9, 10 and 12 is pretty good when he's firing."
His performances for Wales at the Six Nations and the World Cup in the last 12 months have earned Biggar a nomination for BBC Cymru Wales Sports Personality of the Year 2015.
And if he continues his good form into the new year, then there is no reason he couldn't ensure Ospreys go at least one better than last year's GUINNESS PRO12 semi-final appearance.
