Henderson struggled to adjust to his new-found popularity. While he appreciated the support from fans and the business opportunities it created, he grew increasingly frustrated over time as the attention intruded on his private life. In his autobiography, "Shooting for Glory", Henderson stated that the fame left him less satisfied than he had ever been. His frustrations with Maple Leafs owner Harold Ballard, who Henderson felt was destroying the team, contributed to his developing an ulcer. (Henderson later admitted he was not mature enough at the time to deal with the acerbic Ballard). He briefly turned to alcohol as he struggled to deal with his situation. Henderson's professional career reached its lowest point during the 1972–73 NHL season. He had become depressed, and by December, had scored only six goals. He struggled with a groin injury and played only 40 games for the Maple Leafs, who missed the playoffs.
