Cason, a three-star cornerback, flipped from his June commitment to Western Michigan and gave his verbal pledge to Purdue on Monday night. He now looks back with pride on his meeting with Sherman.
"I've always told myself I wanted to go to the best college for my degree," Cason said. "I had no idea [Sherman]was going to come in. You always have that confidence, but you never know what they're thinking. I said to myself, this is a potential offer."
With that in mind, Cason worked toward impressing the Purdue coaches. He put together a stellar first four games of his season, then sent in the film to Sherman. When Purdue's receivers coach brought the film to head coach Darrell Hazell, it was decided that an offer would be made.
Cason couldn't think of any reason to say no. Other factors like his relationship with Sherman and Purdue's engineering program were surely huge factors. But it all came back to his dream of being in the Big Ten.
"I've always had aspirations of playing at the highest level of college football," Cason said.
The easy part was saying yes to Purdue. The difficult thing was bidding farewell to first-year Western Michigan coach P.J. Fleck, whom he committed to in late June.
"It was the saddest thing," said Cason. "It's hard to decommit. They try to prevent you from decommitting. It's a conversation you don't want to have. But I had to be a man about it."
Cason's conversation afterward with Darrell Hazell was much different. He struggled to explain his emotions.
"I couldn't even speak, I was so excited," he said. "I was wondering what to say next; I was trying to prepare my words. I've never had a feeling like this in my life. I'm excited.
"It feels great. It's an accomplishment. It feels like a heavy weight has been lifted off my shoulders."
It was a dream come true for Cason to become a Boilermaker. He'll get a chance to play at the highest level of college football.
"I've been humble and waited for this moment," he said. "It finally stepped up. I'm a very blessed person."
