The Worst Generation is a group, so are the commanders.
That is like saying all Shichibukai are the same lvl while Mihawk alone could stomp old Shichibukai team by himself.
Luffy,Kid,Zoro and Law play a whole different league then Apoo,Drake and co.
People used Urouge to hype Drake and Apoo, fact is that Oda kinda give Urouge a different threatment then for Drake and Apoo.
Also fact is, a hella nerfed exhausted Izo almost defeat both CP0 members in a 2vs1, something with Drake+Apoo+Two Numbers fail to do. A fucking injuried Izo did it, a fresh one would beat both at the same time.
By Portrayal Oda legit show Izo capable to take two WG members at the sametime, yeah it sound pretty not right but that is what we got this chapter.
People downplay YC commanders and veterans, imagine what Vista or Marco would do, perhaps beat 2Cp0 members+Drake and Apoo together. And the portrayal make sense, based how easily Pero handle Capone strongest form.
