It's more of a knock on his ability to create than passing skill. Hes good at coming out of the zone and outlet passes. It's when hes the QB in the offensive zone that nothing of note happens quite often. Maybe if they had to respect his shot hed have more space, as Hench mentioned, but alas. I don't think he helps himself by taking an extra second either, and its really easy to see where hes going to move the puck.
This is basically the reason he does not produce more. The shot, and lack of awareness/creativity.
Honestly the entire team has a problem with telegraphing passes on the power play to be frank. It drives me bonkers.
Well now we're talking about something else entirely.
He's not as good of QB as Makar, that's for sure. I think you're underestimating how big of an impact a quality shot can have though. Look at Makar for example. When you have a wrister as lethal as what Cale has from the point, it means Defenders really have to respect that shot more. They have to move much faster to try and get in the lane to not leave the shot open. It creates more space for passing lanes, like a tonne more as well. But when you have a weak shot, Defenders(Especially on the PK) are able to cheat a lot more towards the pass, instead of getting the stick in the shooting lane they can put the stick in passing lanes more.
But at the same time... Gs PP stats are pretty solid as well. He has 13 PP Point and 1 PPG. His 13 PP Points ranks 22nd in the league among Dmen. Ahead of some pretty damn good PP QBs. Tyson Barrie(12 PP Points), Mark Giordano(11 PPPs), OEL(7 PPPs), Morgan Rielly(8 PPPs).
He is a solid offensive guy. He just is. The stats back it up, the numbers back it up, the eye test all back it up. He's not Cale Makar offensively, and never will be. But that doesn't mean he isn't high end. On a lot of teams in the league, he would be the QB for there top PP. Likewise with his defensive game.
He is just a tremendous two-way Dman. Bordering on legit Top pairing already at 21 years old.
