The one who puts down the pitcher

Shalom Rabbi Michi
The Gemara in the chapter on the subject brings three justifications for the first law in the first mishna in the chapter on the subject. Rav, Shmuel and Rabbi Yochanan. When Shmuel and Rabbi Yochanan explain that the exemption in the mishna stems from the fact that the harmer could not see the jug, whether it was dark or if the jug was at an angle, Rav, on the other hand, believes that there were many barrels and he was forced to break them.
My question is whether a rabbi will necessarily agree with the validity of Rabbi Yochanan and Shmuel and vice versa. Apparently, Rabbi Yochanan and Shmuel are talking about the same principle that the urn cannot be seen, and therefore they may agree with each other. But the question is whether they will agree with a rabbi and whether a rabbi will agree with them?
