I estimate that over 50% of upsets could have been avoided!
Let me explain...
 
 
 
 
As soon as the upset happens, there is usually a whirlwind of excusing flying all across the gym.  Some of them are non-sense.  Some of them are legit.
I have often heard excuses like…
“I didn’t warm-up before the match.”
“I thought he was easy; I won 3-0 last time we played.”
“I was just so hungry, that I couldn’t concentrate.”
“I started off the first game just trying out some new fancy shots.”
