@desa:
Maybe but the way Brown beard phrase it made me think it was about how they wreck havoc during the 2 years that followed Whitebeard. And that they were magically at the archipelago at the same time. Earning Luffy a spot and explaining why they are called a "generation".
Depends on why they are group together in the first place. Is about being in the middle of the chaos for the last two years or the period at which they entered NW ? Then Luffy shouldn't count as he was on hiatus(We don't know when Law entered or what he did in the meantime). Is it about them showing up at the archipelago at the same time? Blackbeard wasn't there. The rookie status? Hard to believe Blackbeard was considered as one.
The fame idea work I guess although I found it disproportionate. Grouping the crew of Veterans which killed Whitebeard with the rookies who still have to prove their potential in the harsh NW?
In the last 2 years, all the members of the Worst Generation have been at the heart of the events shaking the world basically.
Blackbeard may have been the most successful, but it seems that all the members have done things over the past 2 years that have been classified as major events that have been shaking the world, from the way Brownbeard tells it.
Luffy/Zoro - So many things, but with Marineford and Saboady right at the top.
Kidd/Killer - has apparently been working to destabilize Big Mom (sinking 2 of her ships shortly before resumption of the series) and from what we saw from his crucifying antics, has probably doubled his body count.
Hawkins - Maimed Brownbeard and ejected him from the territory he had just claimed in wake of WB's death
Law - Sent 100 pirate hearts to the WG and became a Warlord, as well as masterminding the "Rocky Port Incident", whatever that is.
Drake - Brashly attacked the subordinate of a Yonko and appears to have become said Yonko's subordinate.
Bonney and Apoo we haven't really heard about yet, in terms of what they've done over the past 2 years (although Apoo's major bounty raise suggests that he has been VERY busy). Bonney also escaped from the WG again, which seems to be a crisis in and of itself.
Bege and Urouge we haven't seen or heard from post-timeskip.
In short, it's all very impressive and we know very little at this point.
