According to coach and mentor James Barrett, Whitehead put in a ton of work in the gym in order to have the summer that he did.
"He had a great summer," said Barrett. "You could tell he improved a lot, and he was in better shape. He got hurt during his sophomore season, so I think last year going into the summer he was behind. He just went into the summer with a lot of confidence and played well."
Specifically Whitehead really improved as a shooter, and that came from repetition when no one was watching.
"He just put up a lot of shots," explained Barrett. "When we did have off days he would be in the gym putting up a lot of shots. I think that made him confident because he put up those shots in the gym."
The offer from Indiana came last week, and it is one that Barrett and Whitehead took immediate notice of.
"The fact that James Blackmon de-committed, that is the pitch that they used," said Whitehead of Indiana. "They don't have a whole lot of guards. They have a lot of forwards. They are losing a shooting guard and a small forward, so they are looking for Isaiah to play immediately and it could be a good situation."
Another school that had a de-commitment was Louisville. While the Cardinals never exited Whitehead's recruitment, now they have another backcourt scholarship to use.
"The thing is Louisville never stopped recruiting Isaiah," said Barrett. "Even when they had Quentin Snider they were recruiting him, so it isn't like they re-started recruiting him or anything, they have always been there."
For now Whitehead is going to take things slowly. The next step is for Whitehead and his family to set up some visits.
"He is going to play in the Elite 24 Game, and then we will sit down and map out what visits he is going to take," said Barrett. "He will probably take an unofficial visit to Syracuse and then an official to Indiana for sure."
Whitehead is currently ranked as the No. 17 overall prospect in the class of 2014.
