When I spar newer guys, I tend to focus more on blocking/slipping/countering. When I spar better guys, for some reason I tend to focus on attacking and applying pressure, and my defense kinda becomes secondary. Probably shouldn't do that anymore. One thing I've been doing lately when sparring better guys is trying to remember specific good punches/combos/defensive skills/etc. that the other guy does or has so I can either think of ways to neutralize it next time, or try to implement it into my own game.
