When they first introduced the speed with the ball rating, I thought it was odd, that some players would be faster with ball, than without, because it dont work that way IRL.
I just treat it as another hustle attribute. Because there is players, who are lazy and typically only go 100% out when they have the ball in their hands. I realized I could actually edit Harden, to play more like himself, as he isnt one who usually exerts a lot of energy unless the ball is in his hands,lol, and you could say the same for Westbrook at times too,lol.
Plus you take players, that tend to have to use a lot of energy offensively because the supporting cast isnt great, even if that said player is a solid defensive player, at times, they will take a play or 2 off once in a while on the defensive side of the ball.
So instead of editing it down the speed with ball rating, so its a little lower or the same as with ball, I treat it like the hustle rating, when Im editing rosters, and draft classes. With default 2k rosters, the hustle rating has always been way to high IMO for a lot of players, so its 1 of the main attributes I edit way down on certain players, that tend to be lazy, like Okafor, is known for, as well as Wiggins. But a player like Harden, you hate to lower the Hustle rating too low, and same with Westbrook, because it will impact areas like rebounding and even steals to some extent too. So this way, I dont need lower Hustle rating way down, for Westbrook and Harden, and instead can just given them higher speed with ball rating, than their speed without ball.
