"Tekerman joked that Robert is so indefatigable in the batting cage that his presence is sometimes discouraging to his younger clients, convincing them they'll never make the majors if Robert represents the sort of work ethic necessary to play at the highest level"
"He’s a mentor to his teammates, especially the younger ones, with great work ethic and a great sense of humor.”
"It speaks to his work ethic, which speaks to how great he can be,”... “He’s got a really good work ethic. I saw it in the spring, and I was like, ‘OK, maybe this is (just because it’s) the spring. He’s getting after it in the spring.’ He gets after it every single day."
“He practices extremely hard. He’s extremely focused.”
"“What he does defensively, offensively. What he’s capable of doing, and certainly on the basepaths, we just love Luis Robert.”
"He shows up every day very motivated. Sometimes in baseball it just clicks and you don’t really know why. But it’s certainly not going to click if someone doesn’t have the right work ethic and that’s not the case with Luis. He’s a pro and wants to get this right."
I could add more and more quotes from various times from various people, but I think you get the point. Imagine still questioning Robert's work ethic in the year of our Lord 2026.
