Draper expressed optimism about their ongoing work together despite the physical setbacks interrupting their tournament schedule.
"So yeah, we're on a journey together, and I think there's so many improvements in my game and so much to come," said Draper.
Media reports before the tournament recorded positive moments on the practice court before the withdrawal occurred.
"Draper just won a practice set 6-1 against Shelton.
Jack's left arm and serve looked sharp; coach Murray is also pleased with his return of serve," said Christian Court, courtside observer.
In contrast, Court pointed out that Shelton struggled during that same session ahead of the tournament's opening rounds.
"Shelton's forehand was very out of sorts. That's something to watch next week (against Ethan Quinn in the first round)," said Court.
Following his press conference, former tennis player Greg Rusedski voiced his opinions on whether Draper deserved a main draw wildcard for the year's final Grand Slam on his podcast Off Court.
"Craig is a smart man, and you need to keep the top players happy," said Rusedski.
Rusedski argued that Draper's presence alongside Murray would create significant attention at the tournament.
"If Jack is healthy with Andy Murray, that still creates a lot of buzz in America if you have that relationship in New York," said Rusedski.
He outlined the criteria he believed the USTA should use when deciding on wildcard entries.
"So if the form’s there, yes, he should get a wildcard. If the form isn’t there, then it’s a no.
