Danault currently stands at 3 GF, 5 GA for a 37.5% GF%, 7th amongst Kings forwards. If you just look at 5 vs 5, then he's 5th, but this is a player getting major minutes in all situations. 2 GF 2 GA in 79 minutes 5 vs 5. That tells you that few goals get scored when he's on the ice on both sides. You know who else had stats like this? That's right, Nick Shore.
I'm gonna say this again. PDO is not "luck". Good teams with winning records almost always have good PDOs. Bad teams with losing records almost always have bad PDOs. Good players who regularly make positive contributions to their team generally have good PDOs. Players who aren't helping the team on both sides of the rink generally have PDOs below 1. Look it up yourself. There's very strong correlation between team PDO and point percentage. Sort any team's roster by PDO and you'll see who thee best players are on that team.
Danault is middle of the pack amongst forwards in PDO, and few goals get scored when he's on the ice. If any of this makes you happy, then you must like boring hockey and games that end with the score 2-1.
Again, I'm not saying that Danault is the problem. He's just not doing much to help or hurt the team. He's not doing much at all. He's just kinda...there. It's early, but we're already 7% through the season. I'll be happy if he puts up two points the next game, but the Kings need more out of a 2C.
