The offer is of particular interest to him because of the ties he has to the Bolermakers.
"I haven't visited Purdue yet, but I was born in Lafayette and have connections with the school. Most of my family members attended the school. I was kind of brought up in a Purdue family."
While the Boilers made the first big move, there are many other schools also recruiting Knight.
"Other schools are Michigan State, Indiana, Illinois, Cincinnati, Minnesota and North Carolina State. The only school I have visited is Indiana. I visited once in the summer for a practice and once for a game against Illinois."
More offers should come once schools can see the improvements Knight is working on as he looks to change his body while keeping the attributes that have helped him get to where he's at.
"This offseason needs to be huge physically. My mentality is going to be the biggest thing in order to have a great offseason. I plan on adding good eight without losing my speed and quickness. I think why I'm having success on Friday nights is because of my feet. I plan to improve on quickness even more this offseason."
Another big part of the offseason will be to hit the camp circuit.
"I haven't scheduled any college camps yet, but plan to attend either NFTC or NFSC and FBU. I also home for an invite to the U.S. Army All-American Bowl."
