To answer the TS question...Off that list, I would say Cus\Tyson...IMO, Cus was more than a trianer to Tyson and Cus got the best results out of Tyson out of those other IMO.:good
Tyson & Rooney. Cus was a great mentor & father-figure for Mike & taught Kevin Rooney everything he knew, but he died in late '85. Plus it was Rooney who was his trainer & in the corner ( '85-'88 ) giving quality advice/support during fights.
That's the one for me too. A long association with many ups and downs. Second for me would be Cus/Tyson. Cus kept Tyson grounded and on track. After Cus died, it didn't take long for Tyson to split from that camp and take up with King and his road to bankruptcy and ruin.
