The challenge in the offseason was for Miller to improve his mid-range and long-range jump shots, and he spent hours upon hours shooting hundreds of shots each day.
He will unveil it to the public Sunday when Rutgers hosts Rutgers-Newark in an exhibition game (2 p.m.), and the 6-foot-6 junior is confident in the latest addition to his game.
"It gets to the point where coach Rice has to tell me to stop shooting jump shots and to go to the basket," Miller said. "I can get the ball on the break and if the defender is not going to close down, I can shoot the ball. My teammates are doing that in practice, and I'm using that against them and going by them and making plays for myself or others."
Miller's athleticism and length is an asset in so many areas, but his poor jump shooting limited his offensive maneuverability in his first two seasons.
Miller can break a defender down off the dribble, but that was countered when defenses played off of him because of a lack of respect in regards to his jump shot.
As a sophomore, Miller shot 41.7 percent from the field, including 22.2 percent from 3-point range. That was after a freshman season in which he shot 4.16 percent from the field, and 27.9 percent from 3-point range.
Those statistics are the reason Miller, just like former teammate Jonathan Mitchell did the prior season, spent countless nights inside the Rutgers Athletic Center throughout the summer.
"I would come in and shoot all night," Miller said. "I would be with one of the (student managers) and he would push the ball up as a guard, and I was spot up and catch the ball and shoot. I would eat and sleep here for a day.
"I shoot the ball so much that it's to the point I'm so comfortable in practice, that when it's time to play, I can make those shots."
Not even when school started Sept. 1, nor when practice began three weeks ago, did Miller's routine change.
"Every chance I get before classes or practice," Miller said, "I'm with (an assistant) or one of the managers shooting the ball, or working on other aspects of my game."
