Ballard was in prison for tax fraud when the Toros came to town (and really that was an ownership battle anyways, since Basset was a part owner of the Leafs, had a fight, left, and came back to town with a WHA club in tow)Unlike the Raptors who were only gutted once, the Leafs have been gutted four times. It started when Harold Ballard allowed Bernie Parent to jump to the WHA. That's a much tougher road to come back from. Muzzin is out for three weeks.
They hated each other and so many stories of what happened when Ballard was paroled and came back to the Leafs.
The NHL clubs had standing orders to not negotiate large dollar salaries for players who wanted to jump ship
Plante was still riding out his contract with the Leafs anyways (you know overpaid long term contracts for old players; sound familiar?)
I'd say blame Philadelphia more than Ballard
Philly traded an unhappy Parent to Toronto who promptly left for WHA
He returned in less than a year (demanded buyout during playoffs) and decided to resign with Philly
He then promptly won 2 cups
