Finishing his junior season with 47 tackles, 11 tackles for loss, three sacks, three fumbles caused and two fumbles recovered, Allen has earned 12-plus scholarship offers, including a recent offer from Michigan.
Although there haven't been any new schools coming into the picture, Allen, a four-star prospect and the 23rd-ranked defensive tackle in the country, has been making opposing offenses cringe at the prospect of trying to block him.
"It's hard to make an impact at nose guard, but I feel like I am making more of an impact than I ever thought I could," Allen said. "I think definitely think I am doing more from down to down than I did since last year."
Although he isn't planning on making his college choice until December between his four favorites (Minnesota, Notre Dame, Stanford and Wisconsin), Allen is starting his tour of official visits, with the first one being to a familiar journey down I-94 to Madison.
"I've been to Wisconsin four or five times now," Allen said. "It's a lot easier for me to take unofficials to Minnesota and Wisconsin with them being so close, but I am hoping ask more in-depth questions about academics and other things. I also am hoping to see a good game on Saturday and get a chance to speak with the coaches."
Being recruited heavily by offensive line coach Bob Bostad, Allen has a good gauge of how he would mesh with the program's coaching staff and its players.
"We have a really good relationship. I feel really comfortable with him," Allen said of Bostad. "He's a calm, serious guy, but I feel like he's someone I can talk to. They say that I fit into the program and after meeting some of the guys and spending time with them, they seem like good guys and guys that I would hang out with."
Although he's tentatively scheduled an official visit to Notre Dame for the Boston College game on October 24, Allen plans to take an official visits to Stanford and Minnesota and possibly a fifth, although he hasn't decided where.
With a clear top four in his mind, Allen doesn't have one favorite school, something the talented defensive tackle is content with as he mulls over his decision.
"I think it's good that I don't have a favorite because I can really compare and contrast the four different schools," he said. "I think that will ultimately help me make the right choice."
