Is there an easily accessible database which allows you to view career splits for a player under a certain age?
Like, say I wanted to see a player's basic and advanced stats from the years 2002-2008. Or their stats prior to the age of 30. Or their stats under the age of 29 excluding their rookie seasons.
I ask this because most players have their roles change throughout their careers but we get caught up in the career totals for stat comparisons. Like, I was looking through the NBA finals thread and I noticed there were discussions involving comparisons between KG, Duncan, and Dirk on their career regular season and playoff averages, despite differences in games played, ages, and, well, distribution.
IE: I'd expect KG's playoff averages to be lower than Duncan's and Dirk's because the vast majority of his playoff games have been with the celtics, on the back-end of his career. And I'd expect his regular season numbers to have had a sharper drop off than those of Duncan and Dirk because of the change in his role.
Similarly, I'd expect Kevin McHale's numbers to spike rather sharply during years 6-9 because those are the seasons he was a starter rather than a 6th man. His "prime" would be from ages 29-31/32, rather than 27-30.
