"As soon as I committed, it was a sign to me that I had to get in the gym and get college ready," Marshall told Badger Nation. "I am trying to take my game to the next level."
In Marshall's eyes, getting college ready equals long hours in the weight room and on the court. Whether it is late-night sessions by himself or spending time with the Mac Irvin Fire, Marshall has rarely gone through a day since he committed without some kind of basketball activity.
"I need to improve my skills to get ready for the Big Ten," Marshall said. "There's no reason I shouldn't be consistently working out because I want to fit in (when I get to UW)."
Recruited by assistant coach Howard Moore out of Brooks College Prep in Chicago, the ultra-talented lead guard picked the Badgers over the likes of Arizona, Arizona State, Baylor, DePaul, Xavier and Wake Forest. Marshall has started since his freshman year and has been compared to the high school version of Jordan Taylor, except with longer arms and a better shot.
"It's a fair comparison," Marshall said of him and Taylor. "We both have similar games. We are both able to create our shot within the scheme of the offense. We both really value the ball. I don't like turning it over a lot."
That notion of ball security was instilled in him with his time on the AAU circuit with the Mac Irvin Fire, a team chalked full of talent. It's been so beneficial to his development that Marshall, sidelined the last two weeks with a minor injury, is counting the days until he can rejoin the team at the Rookies Invitational in Houston next weekend.
"It's a real good feeling playing with all those elite guys on one team," Marshall said. "Just to lead a team and be a point guard on a team like that is real exciting and makes me a better player. I always play wanting to play against the best competition, so it's preparing me to play in the Big Ten. Hopefully, the transition at the next level will be easier so I can get a lot better."
Two of those players on the Fire are athletes Marshall, UW coaches and fans know quite well. Junior Mychael Henry is considered one of the fastest risers in the Midwest and junior Mike Shaw is the eighth-best power forward in the country by Scout.com. Both players have been offered by the Badgers.
"Mychael is a real good player. He can dribble up the court, shoot from deep and has good range and is real strong. He's a great athlete. Mike is a real versatile player. He's 6-foot-8 and can step out to hit the three-pointer or the mid-range jumper. He's real strong inside, too.
"I've been talking to both of them about coming to Wisconsin. I have been recruiting them both."
