Anyone can be knocked out, some can take more punishment than others. However, using Mexican sparring gloves in the gym will make you learn to avoid getting hit often, and when you do, their is a noticable difference between competition gloves and Mexican sparring gloves. Mexican sparring gloves are longer down the forarm, which will dispense the 16 oucnces (this is what I use in my gym) more so than regular sparring glove. This creates less of a cushion over the knuckles, which will result in a more hurtful punch. Regular gloves have more cushion above the knuckles for added cushion, which softens the blow. I am not sure if one can develop taking a good shot, and In all my years, it is mostly the snap of the punch that causes the knockout, rather than a heavy punch with no snap....sound about right? or am I mistaken.......
