"Everyone is even, I can't tell you who I like the most right now," Walker said. "Wisconsin was a great trip, it was way better than I thought it would be. On one hand, I'm glad I took the trip but it sure makes thinks a lot harder for me. That's a good thing though, they have a great football program, an incredible fan base and a great group of players and coaches.
"Big 10 football is real big, it's a great conference and I love the passion they have for football out there. Honestly, I took this visit with an open mind but I really thought my decision would be between Cal or Boise State. Now I have no idea what I'm going to do."
Walker's original plan was to make his decision this week, before Thanksgiving on Thursday.
"It won't be this week," Walker said. "I don't have a deadline or time frame, it will be whenever I feel good about it. I have to do my homework on all three schools. I already did a lot on Boise State and Cal and now I have to do more on Wisconsin.
"There are pros and cons to each school. I have to look at those and see what risks I'm willing to take with each school. Cal is closer to home but Boise State and Wisconsin play on T.V all the time. Location isn't a factor for me, I'll go wherever I feel the best school is. It's going to be a tough decision and that's why I'm taking my time before I commit anywhere."
