That's just your assumption, don't think that Chan/Goh is better than Goh/Lai at all.
Bad move by BAM caused everything to fall apart in the first place.
They should be ashamed of this silver, a memento of failure.
Come on bud, you win some you loose some, they gave their best it's just sometimes not everything goes according to your plan.
Dissapointed? yes it's natural, "ashamed"? Cut 'em some slack
Also, they went by the script, silver for #2 seeds, every tourney is a new one, which starts from level 0, you can't sit and "plan" stuff according to previous records.
PS: my assumptions? What else can we do, who knows what would've/wouldn't have happened if the team organizers not "screwed" up (according to you).
Did you predict GLY/CPS coming from that long injury and still perform way above their conditions, when it mattered the most, Olympics? No but they did, organizers gave benefit of the doubt to them considering they have higher accolades at major stages and are more experienced.
It was a risk, sometimes they pay the dividends sometimes they don't.
