I totally agree with that. Tony wanted everything Sosa had, but he was too hot-headed and often irrational to keep it!
He didn't think things through like Sosa did, and take Franks advise to remain "low key" so that he could last a long time.
That is how Sosa lasted so long(not by Frank) but by being low key and not trying to "have it all".
Yeah,Frank was surprisingly quite smart.But the stupid bastard hired retards to "do the job" on Tony.
