This entire discussion makes no sense because power scaling in DBZ is retarded. Goku was grazed by a bullet long after surpassing universe busting levels, yet a bullet couldn't even harm kid Goku.>Muh element of surprise tho
He was a fucking Chinese redneck who had never even seen a gun, let alone be aware that bullets kill people.
And then there's the fact that Roshi can somehow take on opponents who are SSJ3 level at least.
Going by that highly inconsistent power scaling, it's not unlikely that Boros could wreck some shit in the ToP. He'd still be far weaker than Jiren, but he could knock some jobbers out.
