Just like in basketball-reference.com great stats for the NBA, a player's Career stats per year highlight in Bold if the player was the leader of that category in that particular year.
for example, if you check John Stockton, you will see EASILY which (and how many) years he won the Assist title (either per game or total assists) with a quick look of his Career Stats.
In BuzzerBeater it is impossible to pinpoint easily when your player has won any Stat title. As a minor suggestion, I would add to the Player Stats page in Bold whenever he won any title: scoring title, rebounding title, assist title, steals title and turnovers "title". Also Rating title would be nice.
If that is not possible, or to hard to write in code, then I would add it as a special mention in the Player's History Page, as another filter besides Triple Doubles, NTs game, etc. Some "Individual Titles", and then mention "Event: Assist title", "Season: 38", "Details: Won Assists per game title with 11,2 APG" or something like that.
Besides the nice detail of knowing what your player has won, you can also imagine how he dominated a league in a particular season.
