he makes very slight changes. to the point that it is difficult to notice without having them side by side to compare.
iirc the back plate last year was when he added the LA graphic. i remember him switching it out between period's in a game because of a fit issue. he went back to his old one iirc
this year's mask has Kings crown logos on the forehead crown and the backplate, last year's mask didn't have that. the painted cut out notches on this year's mask now has a mesh type design worked into them. last year's mask were just full black with nothing in them.
it is small cosmetic changes like these are what he seems to do. is it the coolest design out there? no. what it does though (especially if he continues this), will be over time establish an image that will be iconic with J Quick. in 20 years from now you will think of the Knights helmet design as being JQ. the same way us old farts can identify and recall other iconic masks of keepers.
Beezers cat mask, Dryden's oval striped mask, Cheevers stitches mask, Roy's 'Lanche mask, Brodeur's NJ devil tail mask, Parent's all white with 2 Flyers logos only, etc.
