The MVP system allows you to assign most valuable player points on a match by match basis.

First off you need to make sure you have MVP points enabled in the division settings (via the setup menu and 'details' against the division).

Once enabled, a new column will appear on each match scorecard - allowing you to assign MVP points to each player on a match by match basis. You can use this to assign a player of the match by giving them 1 point. Alternatively you can assign points based on the player's match performance.

You can then view the points via the MVP Points report. This can be filtered by season or date range.
