my player takes his hand eye coordination very seriously, as it can be pretty useful to have exceptional hand eye in hockey. whether it's batting pucks out of air or tipping in a deflection goal. some really good practice is to keep it simple and just practice tip in goals. need to bring out your inner chris kreider cause he is an absolute dawg at tip ins. i see some goalies work on hand eye by throwing a bouncy ball up against a wall and catching it, so i am sure that could be helpful too. i think practicing baseball might help hand eye, it takes an insane amount of hand eye to bat at a high level, if you can get that down it can probably make deflecting pucks a lot easier. my player is not around the front of the net all that much so he does not have to go crazy with practice but it can be a nice way to round out his offensive game, to prove himself useful in all aspects of the offensive zone
