Although he played only half a game in the NHL with the newly-minted St. Louis Blues, during the 1967-68 season, Caley once had a shutout streak of 189 minutes with Phoenix in the WHL during a later part of his career.
He suffered a serious whiplash injury in Febraury 1970 when he stopped quickly at a crosswalk and the car behind rear-ended him. He missed the rest of the season but recovered in time for 1970-71. He retired at the end of the 1972-73 season to become a dentist, returned the next season when he felt he could juggle school and pucks at the same time, and retired permanently after seven games in 1973-74 when he realized he couldn't handle the two at the same time.
Caley was one of very few players to play junior in both Ontario (with Peterborough) and Saskatchewan (with Weyburn) before making the NHL. After his year in the Blues organization, he was traded to the Rangers though he never made a trip to Madison Square Garden. He went to Phoenix of the WHL, and it was there that he played his final games before practicing dentistry.
