Actually, I believe Torts has been most successful with young teams. Rebuilding Rags, rebuilding Columbus, Tampa when they were developing into champs. He completely flopped with a veteran team in Vancouver. And he had great success in Philly UNTIL, as others noted, he crapped on and humiliated the veteran captain.
Veterans probably tire quickly of his ego and his abuse. Young players, hungry and eager, are probably more willing to follow him, especially when his demanding style has them suddenly winning games after years of failure.
He's a jackass in my book, anyhow, so I'm not shedding tears over his problems.
