OWN GOAL

1st time in my life i saw a real own goal in b.ball ( live 1 )
today after my class went down to the b.ball court to watch the game between
SOEAT 1 vs SOBA
2 own goals in the game...
very embarrassing i guess...
last time wong almost done it once and attempt once
but he FAILED to "score"
today Bruce and JR from SOBA done it oledi!!!
it was so weird when JR score that one...
hardly for me to believe it !!!!
today JR play so well but that 1 spoil all his performance...
pity JR...
why they will make mistake like this one ? ? ?
over pressure or what else ? ? ?
could not figure out of it !!!
