You can mount a basketball hoop to a brick by using a drill bit specifically designed to penetrate tougher material. Try a concrete or masonry bit, and don’t forget to drill your holes the depth of the long sleeve.  It’s also important to note that while you may think the tighter, the better — especially with brick— you can run the risk of stripping your screws, warping your mounting bracket, or cracking your brick surface. Make sure your hoop is fasted properly, right in the sweet spot, not too tight but not too loose.
