Just to follow up, why not to tell us a bit about your game? 2D, 3D? Top down? Control a whole team or a single player?
Playmaker can work as an animation controller (tells which animations to play when based on your button input). However, it is not an animation creator. Ie, you would still need to make, buy or go to a studio to capture animations. If your game is 3d, it might be hard to find to buy animations that are for hockey. So that might be something to consider before getting too invested in a specific idea (if this is your first game).
For example mixamo is a popular place to get animations these days, as they are currently free:
https://www.mixamo.com . You can sign up with an adobe account (free). They have a ton of animations, but I dont think any sports ones??? You can check.
Maybe this one is best?
