This can't be a coincidence, its quite systematic.
I wouldn't call it crumbling. They often times overperform in groups because they beat tier 2 teams consistently but when it comes to actually strong teams they just get outclassed, because firepower can't cover for the lack of good tactics anymore.
3 biggest issues I see are:
1. the stellar strats that worked in group stages are NOT even tried during playoffs - not sure if it because they are constantly afraid of getting anti-strated or they just don't practice for groups
2. losing against eco's
3. non-existent nade damage to opponents
