It's unprecedented territory for the NBA which has strict rules around when and where scouts can watch future draft picks.
Scouts aren't allowed to watch players in the US college system while they practice with their teams, but they are allowed to watch and observe them at organised Pro-days.
The 70 scouts believed to want to view Hampton during his time in Memphis are also in town to observe a pro day hosted by college team the Memphis Tigers so they can see projected number one pick James Wiseman.
Scouts value there time viewing players outside of games.
"For NBA scouts it's very important, they'll watch the game but they want to see how RJ acts at training, how his teammates training – If you're a top ten pick right off the bat the team is investing 25 million in the player, and the assumption is they'll invest another 80 or 100 in extensions." Walsh said.
Walsh is confident this 'grey area' will be resolved before the Breakers train today at 11am [NZT].
"I believe, or at least I'm hopeful that they're going to take an objective look at this and say 'hey this slipped through the cracks, this is a professional athlete, professional scouts want to watch him, let's open this up.' Right now they just don't have a rule they can fall back on."
Walsh believes the current rules are in place so that NBA teams aren't disadvantaged by being unable to look at players that other teams can.
"But because every single team is represented here, I hope that they will come around."
