User blog comment:South Kaioshin Daniel/What Rank would Zoro have gotten if he joined Borque Works?/@comment-3181121-20110404101714

Pre-time skip strength he probably would have been Mr. 4.

He was stronger than all the numbered agents below Mr. 3, Mr. 3 however could have given him an impressive fight. Mr 2s DF makes him a much more useful tool in a Mafia-style organisation such as Baroque Works, because information and more importantly misinformation are tools that are of more importance when you're trying to organise an uprising than brute strength. He only learned how to cut steel during his fight with Mr. 1, and thus would have been weaker than him at the time that he'd joined Baroque Works.

There are more aspects to consider, such as, who his partner would be, as the teams usually compliment each other well, and the fact that he would have been the only non df user in the top 5 something that Crocodile may not want(?)
