If Sanada Masayuki of Osaka Battle is still alive, will it change the situation?

Because according to Sanada Masayuki's character, he will choose to surrender directly to Tokugawa Ieyasu.

Sanada Masayuki was called the old fox of the Japanese Warring States Period. He surrendered back and forth between various names three times in his life. His aim is to preserve the Tian Zhen family, and no matter who he takes refuge in, he belongs to the typical "whoever is strong will mix with him". Moreover, the friendship between Sanada Masayuki and Toyotomi Hideyoshi is not deep, so there is no need to fight for the Toyotomi family.

In the case of Osaka War, even if Chinobu Uesugi and Takeda Shingen came back from the dead, it would be of no help, because the strength gap was too great. In the face of absolute strength gap, any trick is a small skill.

At that time, if the Toyotomi family wanted to win, the only way was to surrender early and then remain anonymous in Tokugawa Ieyasu. Both Tokugawa Hideyoshi and Tokugawa Guang Jia died and then made a comeback (in fact, the descendants of Tokugawa were short-lived). Moreover, this precedent in Japanese history is not without hardships.
