[PS: Here I go explaining again. Sigh. I'm not denying Android 17's strength—the problem is, aside from his infinite energy, I really couldn't see what role he played in the Tournament of Power.

[As for Android 18, she herself admitted that her strength had declined a great deal because of raising a child.]
Replacing Tien Shinhan and Master Roshi with Broly and Cell, and replacing Tien Shinhan and Krillin with Raditz and Nappa, Universe 7's fighting strength would be no weaker than that of any other universe.

As long as they found Broly and recruited him into the team, then
