Let's take a look at Duran's WAR the last 3 seasons:
2023 (roughly a half season) bWAR 2.2 fWAR 2.5
2024 bWAR 8.7 fWAR 6.8
2025 bWAR 4.6 fWAR 3.9
Totals bWAR 15.5 fWAR 13.2
We're talking 2.5 162 game seasons, basically.
So his average WAR would be somewhere around 4.5.
WAR is a counting stat, and Duran hardly missed any games in 2024-2025, so he benefits from that.
But the bottom line is, he has played like a bona fide star for 2.5 seasons. Yes, his offense was MIA at times this year, but join the club.
He's a very valuable player.
