"I was up (at Louisville) for an unofficial visit and I just loved everything about it there," Palmer told JCFootball.com. "They were my best offer and they play really competitive football there.
"Coach (Bobby) Petrino is a winner. He wins everywhere he goes and I really liked the offensive line coach (Chris Klenakis) there too and I really liked how they called their o-line 'The Union'. You put in your work and then after you get graded in a game, they give you a union card and you are part of it from then on."
As far as shutting things down, Palmer is adamant he is happy with his decision, but he did say that he isn't completely shutting things down.
"I think it would be naive of me to say that I won't listen to anyone else," Palmer said. "If it's the perfect situation for me, then I have to look at it.
"You can't say something is perfect until you actually see it, so, I will just say, I am happy with my commitment to Louisville, but I'm not completely shutting it down."
As a prep at Sheridan (Thornville, Oh.) High School, Palmer had one of the top programs in the country interested in him, but unfortunately he wasn't able to qualify.
"Ohio State was recruiting me pretty hard, but I wasn't going to qualify, so they actually sent my tape out to a couple of schools out in California and I had a choice of Saddleback, Pierce or San Bernardino and I chose San Bernardino.
"I was playing opposite of Paul Ramirez, who signed Arkansas, so we made a good tandem out there, but after I finished the quarter, I needed to leave because I spent a ton of money that I didn't have since California junior colleges don't give scholarships and I wasn't eating right because I had to skip meals and stuff and I was down a lot of weight and I just needed to change, so Butler was the right place for me and I'm happy I made the move."
Palmer is on pace to finish up his two-year degree in May and he will have three years to play two following the 2016 football season.
