"Things are going good really good," said Koehler. "I had trimmed it down at the start of the year, but it has gone through some changes during the year. Right now it is Tennessee, Kansas, Oregon, California and Hawaii."
Koehler is looking to take official visits to each of the five schools on his list and got started a couple weeks back.
"I visited Kansas two weeks ago versus Texas," said Koehler. "It was a real nice area. It was nicer than I expected. I liked that it was a college town, everything is based around the stadium."
"This week I am going to Tennessee," said Koehler. "I am thinking about going to the Oregon in a couple weeks (11/17). Then I will take visits to the Cal and UH in December."
The 6'3" 330lbs lineman talked about what he looks for while on official visits.
"First is what the sports can offer to help me through college. I have ADHD, so who can help me with academics," said Koehler. "The relationship I have with the coaches, then the coaching style. Lastly, about family and who is around there."
One program that may have an advantage is Tennessee. Not only does Koehler's grandpa live near the campus, which allowed him to visit unofficially this summer, but his teammate linebacker Colton Goeas is already committed to the Vols.
"He's been trying to recruit me the whole season (laugh)," said Koehler. "I keep telling him I am wide open. He is going on his visit in December so he can get more time with coaches."
Koehler talked about where he thinks his game improved during his senior season.
"I think skill wise and dominance wise it I was the same this season," said Koehler. "People stayed away from me, didn't blitz at me. What I learned this year was how to do film study and how to come to line knowing what the defense would do. I improved my football IQ."
