Being fast helps some problems, but can cause as many as it solves.
"It helps if you get beat because you can use your speed to make the play, but sometimes I kind of have a problem with it because I rely on it too much," Kyeremeh said. "Someone gets behind me and I can't catch up or I close too fast and he makes a move and I can't get him."
Roberts wants Kyeremeh to eliminate the margin for error and to close the gaps the opponents can sometimes exploit. He's hard on his players, though with a purpose, but he's especially hard on Kyeremeh, as well as fellow freshman Ricky Rumph.
Roberts will make Kyeremeh repeat drills to get it right, or to get it right twice in a row. He'll call out to Kyeremeh by his jersey number. Sometimes that's because "Seven" is easier to say than Kyeremeh, but that doesn't explain when Roberts calls the player "Nana."
The lessons and the language can be pointed, which is a deviation from Roberts and who he is. Quite frankly, it surprised Kyeremeh at first.
"I didn't expect that at first and it kind of shocked me, but I didn't get yelled at that much in high school, either," Kyeremeh said. "But he gave me a reality check and reminded me I have to do my job. I think he sees the potential in me and wants me to focus on the things I need to be focused on."
It's not natural from Roberts, a former class president at the University of Texas and a Harvard Law graduate, but it's not necessarily an act either. He's intense with an idea in mind and that can mean being mean. What Roberts has learned is Kyeremeh is "mentally tough" and can be trusted in environments that will require trust.
"He has a high tolerance for criticism," Roberts said. "When it comes to freshmen, when it comes to most players, I understand that we're going to be playing in some very hostile environments. I need to find out as much as I can how much they can handle. Right now.
"They're not going to be that friendly to us in Oklahoma State. I have to try to push as many buttons as I can now and then figure out how far I can go with each player."
