Characters in One Piece are capable of being stalled by way weaker characters. Bellamy was capable of staying Luffy for more chapter counts than Lucci did to Zoro. Zoro got stalled by Monet for quite a while. So there's nothing special there, and the reason we say it was easy for Zoro is same reason why it's obvious when he's being stalled solely for the sake of the plot. Zoro has never used a named attack against Lucci until Chapter 1110, and as soon as he does, the fight is done. This has the same beat as Monet, Pica, Hyouzou, Kamazou, and Apoo in that his fight with them became completely one-sided as soon as he actually started to use moves in his arsenal.
This is completely different from "stalling" opponents like Cracker and King, where for both Luffy and Zoro respectively, they actually had to be serious from the start, using named attacks from the jump, and the opponent could withstand, and even counterattack said named attacks. Cracker and King were formidable, Lucci wasn't.
