Xbox One allows you to remap the controller buttons if you feel that the default settings are having a negative impact on your average high score. Open 'Settings' then 'All settings', and choose 'Kinect & Devices' then 'Devices & Accessories'. Choose your controller and select 'Button Mapping' (you can also check for controller updates here).
You're then free to remap and reassign buttons as you see fit. The configuration options also let you invert the Y axis on the left and right sticks and even swap the sticks or the triggers around. If you get yourself in a confusing input mess then the 'Restore Defaults' option on the menu lets you quickly get back to the standard Xbox One control settings.
