Carrigan competed in the Mexico Olympics fall of his senior year. He had a great shot at medaling, but got screwed over by an old rule that said if the pole went under the bar it was a miss (the rule was changed shortly thereafter).
Carrigan also made attempts at World Records while in high school.
The biggest thing against Carrigan is that the event was rapidly evolving at that time because fiberglass poles were so new. But 17-4.75 is still an extraordinary mark by a high schooler!
I am going to say 19' on the old pegs or 18'9" on the new ones for Tommy would put him in that amazing range. But that is just my opinion
