The biggest thing that's overlooked when selecting your drivers, is that they will be representing your team at any given competition. Yes, Skill is very important. Yes, strategy is very important. Knowledge of the game, maturity, listening to your coach, etc. are all important, but you must remember that these kids are the ones that most everyone will see-- the ones that the judges will most likely see and/or talk to, the ones that the other teams will most likely associate with, etc.
If the kids that you select are fantastic drivers, know what to do, but have an awful attitude, and aren't graciously professional, the other teams will talk about them negatively. Popular to contrary belief, Robotics is not free from teenager actions such as Gossip and spreading negativity. Obviously, you want your team to be known as a nice team and a helpful team. Now, I'm most certainly NOT saying that drivers are the only influence on how "kind" and GP a team is--many factors determine that. But at a competition, they will stand out the most out of anyone.
In short, many factors, such as skill and knowledge of the game affect driver choice. But one of the most overlooked factors is how do these team members represent your team.
Hope this helps.
