Two Points of View

There is a Mishnah in Bava Metzia that at first glance seems understandable. Yet when the Gemara (41a) tries to elucidate it, it seems that the first law in the anonymous Mishnah represents the opinion of Rebbe Yishmael, while the very next law in the anonymous Mishnah represents the opposing view of Rebbe Akiva. It would indeed be rare for the very same Mishnah to reflect two opposing views without indicating that.
However, Rebbe Yochanan concludes that though it may be difficult to accept, this is, in fact, the correct explanation of the Mishnah, and the Mishnah reflects two different opinions. Rebbe Yochanan exclaimed, “If anyone can explain the entire Mishnah as following one point of view, I will carry his clothing behind him to the bathhouse.” Rebbe Yochanan was in effect saying that if someone is so great that he can come up with an alternate understanding of the Mishnah, he would accept him as his rebbe and carry his clothing after him.
Why didn’t Rebbe Yochanan just espouse this thought clearly and exclaim, “If someone explains this Mishnah, I will attend his lectures and study under him?”
