The Arizona coaching staff knows this and is trying to get a head start on fellow Pac-12 recruiters.
"The Arizona coaches have been recruiting me more and I'm getting to know them better," Cook said. "They've been telling me about their defense and all the different stuff they can run."
Arizona's coaching staff has let Cook know that it believe he has the ability to contribute right away.
"They feel like the linebackers they are recruiting will hopefully be able to play early," he said. "They think I can help them a lot as a blitzer who can also back into coverage.
"They feel my frame will help me do a lot of different things."
Other schools are also trying to make a solid impression on Cook.
"I would say my top three are BYU, Arizona and Hawaii," Cook said. "I like the coaches a lot at BYU. I really connect with what they're talking about and obviously the school has a strong football tradition and is a strong academic place.
"I like Hawaii a lot because of Coach Chow. He's a really good football mind who has coached a lot of guys who have gone on to play in the NFL. Plus anybody is going to be interested in playing in a place like Hawaii."
There are a few things Cook is looking for in a school.
"Above all I just want to play at a school that I feel comfortable with and has a major I want," Cook said. "There are some of the other schools recruiting me on the west coast as well, but right now those three stand out."
Cook is not sure where his recruitment is headed, but he does know when he wants to make a decision.
"I'm not completely sure what my next move or visit will be, but I plan on announcing August 8, so I've got different places I've got to check out."
