The reason it is better is that you know that a 10 star scout can be programmed to give all the positions and other information as well as look at a player numerous times to get an accurate value of the players as a 1 star scout will go out and stare at a game and base potential on that game alone and give you random information on all of the players.
If you dont see a difference than we should get rid of all the staff as well because if you have ever been on or around a proffesional team than you would know that a scout is as important as anyone else. Also you can add into scouting thathe can scout players on other team or the other team to try and get an advantage like profeesional teams do.
The idea behind these game is to make them as realistic as possible. Then have a scout who can do his job proerly.
You got to know when to hold em, know when to fold em, Know when to walk away and know when to run. You never count your money when youre sittin at the table. Therell be time enough for countin when the dealins done.
