Yeah, well Chad's not God, so he can be wrong. Lifting to failure and using high intensity techniques a la Thibaudeau can work too. Besides, in the immortal words of Louie Simmons "a perfectly safe exercise is a perfectly f***ing useless exercise". Translation is--risk is part of the game.
If you're smart about failure training, you won't need to worry too much. For the record, I don't lift to failure most days. But for a guy looking to add size, "heavily fatiguing exercises", as you put it, are the way to go. More microtrauma = more growth if you eat and rest enough.
