Compared to what exactly? How long did it take for the captains to achieve Bankai? It's not like Renji and Rukia had just graduated from the academy when they were first introduced to us. They had already been members of the Gotei 13 for half a century before they achieved Bankai. It also makes sense that Renji and Rukia would achieve Bankai at roughly the same time, since they entered the academy together.
