The former McDonald's All-American from Chicago must have been listening.
Blackshear had the best overall game of his season with 15 points, five rebounds, four steals and a lot of aggressive play in a 113-74 blowout of Louisiana-Lafayette on Saturday at the KFC Yum! Center.
"I thought this was his best game," Pitino said. "And I told him before the game, ‘Son, it's time for you to start doing some thing. You're a better basketball player than this.' He certainly was offensively more aggressive."
Blackshear was just 2 of 6 from the field but was taking the ball to the basket and was 9 of 10 on free throws. He hit 2 of 4 three-pointers.
"I think the last couple of days in practice, I have been more aggressive," Blackshear said. "I'm just trying to play the way (Pitino) wants me to play.
"He just wants the best out of all of us and playing hard really gets you to where you want to go. He just wants us to play hard so we can get there."
Blackshear showed some assertiveness in the second half when he hit a three-pointer from the left corner, pumped his first and then after a steal tried to dunk on a Lafayette player. He was fouled and hit the free throws.
"I just have to be aggressive," he said. "I like playing that way, I just need to do it. I know that I can do it."
U of L freshman Terry Rozier said Blackshear played, "just like the Wayne we knew from high school and how he played."
Now, Pitino said it's a matter of continuing to play that way.
"Your next question is going to be, why doesn't he do that all of the time?" Pitino asked. "I think this is a start of that. I think he realizes right now that he has to do that. I thought he was aggressive on the offensive and doing a lot of good things."
