About a month ago, the 6-foot-5, 235-pound sophomore-to-be named Arkansas, Tennessee, Miami, and Arizona that stood out to him; and nothing has changed on that front.
"Obviously Miami, Arkansas, Rutgers, and Tennessee are my favorites right now," Jackson said. "I'm starting to shape out my top five. I'll definitely have that before the season starts.
"I like Arizona in there also. With Arizona, I definitely like their offense among other things about them. I'll probably visit up there again soon."
Jackson has already tripped to Arizona once this summer, as he made the trip down from Scottsdale to check out what the Wildcats for himself. After visiting, he continues to be impressed with what UA has to offer.
"My visit was a great time," Jackson said. "I had a great time there. They showed me tapes of their past great tight ends, so I can see how I fit in with their offense.
"I like they offense they have. They have a program on the rise, and the Pac-12 is a very respected conference in football right now. There's a lot of appealing things about Arizona, and obviously it would mean staying home in Arizona."
The UA coaching staff continues to work double time on Jackson, as it has sent two of its top coaches out in pursuit of the Gilbert High School product.
"I talk to coach (Tim) Kish, and I talk to coach (Mike) Stoops also regularly," Jackson said. "Coach Kish is a great guy, it's been fun working with him from day one. He's very enthusiastic and he always tells me how excited he is about me as a player. He's been great.
"Coach Stoops just tells me the advantages I would have at Arizona. He tells me about what he can offer me as a Wildcat, and the fact that he has a great history of developing tight ends and getting them to the NFL."
Aside from his trip to UA, Jackson has also tripped several other campuses; although he is poised to put his trips on hold as he prepares for his final season at Scottsdale.
"I just got back from Miami," Jackson said. "I had a great time there. It was a great visit, definitely as good as I thought it would be.
"I don't have any other visits planned right now. I'm going to take a couple weeks and get ready for my season here at Scottsdale and get my summer classes straightened out. I'll probably start thinking about that and taking more visits toward the end of the summer."
With recruiting currently on hold for a little bit for Jackson, it's no surprise that he'll continue to take his time on a decision.
"I don't really have a timetable for a decision, I can't really say," Jackson said. "I would like to make a decision after the season and after I have a chance to go and check out some more schools."
