Show shot speed/skating speed in some modes
Don't remember which year this was, think it was on PS3, but there was definitely a time where you could see your shot speed in one of the practice modes, don't think we've ever had skating speed though as far as I can remember at least. Think it was a shooting drill, like an All-star game style accuracy drill that had the shot speed or something. Would be super cool to get some sort of analytics/feedback like that, even if it's only in Free Skate or Practice.
It would also help us determine what certain abilities do for ourselves and fine tune our builds. Maybe in replays you could highlight a skater and it would show their skating speed somewhere on screen, or during play there could be some analytics showing fastest puck carrier speeds bursts, and any time a shot was taken show the speed of the shot. Idk, something fun to introduce "analytics" back to the game.
Really I just selfishly want it so I can more easily calculate the actual buff to your stats things like Heatseeker, One-tee and Wheels give, ideally you would just explain the actual stat buffs or percentage buffs the abilities give somewhere in patch/release notes, but the shot/skating speed thing could just be a fun analytic regardless of worrying about attributes.
