Yup, and again, even getting 40% with consistent faceoff deployment would be fine. However, he's completely unserviceable. The Jack fan club shouldn't argue with me; go argue with the actual coaching staff that clearly does everything it can to avoid deploying him in a true C role. They don't trust him. It screws up the rotation at ES and forces them to use 1 powerplay unit. That is 99% on Jack.
The other 1% is actually on Fitz. I pointed out the massive risk in heading into this season with the center depth as is and it's already problematic even with a 100% healthy forward core. He needed both Jack to round out his game AND Mercer to rebound production wise plus be a utility C as needed. Oh, and 100% health. Obviously still early and a new coaching staff, but he's only gotten 1 of those 3 things so far.
The folks laughing at this viewpoint are the same that ridiculed those of us who pointed out a defensive core of undersized/soft/ 5'11 guys would be a disaster several years back. At least this org and their brainiac "analytics" gurus corrected that mistake eventually.
Anyway, the faceoff stuff isn't the main issue for Jack. It's the unwillingness to round out his game and continuing to take away his teammates, overhandle the puck, etc. I have to reiterate this so someone doesn't go "you think jack is a BUM because he can't take faceoffs". Doesn't make him a bad player, but it prevents him from being what this org needs to contend and what 90% of this board has laughably already convinced themselves he is. I mean, how do you have a discussion with people claiming his shot is ELITE in this very thread for example? No one that isn't a complete blinded Devils homer would say that, so what's the point?
