What difference could Yamcha have made vs Nappa if not ambushed by the extremely depressed and/or noble saibaman?

So even after Chazou and Tien had died, Krillin and Piccolo alone were able to land on Nappa. Vegeta also says that if Krillin had landed his kienzan it would've killed Nappa. With Yamcha there, could he work with Piccolo and Krillin to make something happen? They need to set up the kienzan, unless you think the spirit ball is enough. Or even short of killing Nappa, how much more success could they have with three of them trying to distract Nappa to set up attacks?

Poor saibaman. Went out like a hero, but the other saibamen's moral was clearly down, allowing scrubs like Piccolo to kill them.

Nothing changes. They were all getting stomped bad. Ten who is stronger than Yamcha got toyed with and survived his Kikoho with minimal damage, which is far more powerful than Sokidan.
