Whoever it was would be criticized if you don't like tuneups. McNeeley was ranked 7th when Tyson fought him, does that make him a better tuneup?
I never said i don't like tuneups. And nobody else is going to argue against fighting a 10-15 ranked guy. That gets Khan ranked, nobody is going to say he's ducking someone on his return fight.
Stop conflating good/bad with rankings. If a shit fighter gets you ranked #5, then fight him. If a fighter gets you ranked #12 then fight him.
