no, sorry I cannot change the pick this is covered by rule #4 on the instruction page.
If the program was set up that allowed me to easily do this then I would. The ONLY way I can alter the data is to literally hack into the program and that potentially puts all the scores/data at risk.
It is not uncommon for someone to make a mistake but the fact that ONE GAME is worth only 3pts and we will have over 100 games it is extremely unlikely this mistake will cost you the overall championship.
sorry
