What I agree about (from the start) is that this suggestion is not a top priority.
But, as I wrote somewhere, it is not that available to scout a player by your own.
Currently, and due to other definition of the game, the MVP of a team may come seconds before playoff begins.
You cannot get enough information from his stats, as they where made on a different league.
A player who was a great offence player (Morisson) may be very bad at that when coming from college into the "bigs" league (NBA).
In addition, what I suggested is that you may scout for a limited of information per week.
And to that I've added that it will cost you.
It adds possibilities and complexity to the game - now you'll need to decide does this information worth it? Do you want to pay money for getting this information or you preffer using the money for other targets in the game.
