It's pre time skip Luffy. Also, Crocodile almost killed Luffy too. Lucci was tough but that was way before... that Luffy could not beat a Pacifista alone (he needed help from all the other strawhats).

Just because Lucci was strong against Luffy he does not qualify to be as strong as an warlord. His abitly is mostly meelee combat, not for mass destruction unlike most warlords.

Law as of now is Capable enough to take down way stronger people than Lucci, Zoro and Sanji can as well. So if CP 0 is like Lucci each they might as a combined force put Law Usopp and Robin problem (as Cearsar would be against them) but that is all they can do in the big picture...
