User blog comment:AYET/(95) The Last Shichibukai/@comment-4374114-20130325150800

I think the biggest issue with Marco being a Shichibukai is that the crew he is over is far too large. I could understand if he was in charge of something smaller like maybe 100 men but there are so many crews that would fall under the WG if he joined. The only way it would work is if most of WB crew had disbanded, which with the brotherhood they had might be quite the stretch.
