But for now, he says he has an early favorite.
"As of now, Western Kentucky stands out," Ferby said. "I hear a lot of great things about Coach Petrino, and I know he did great at Arkansas.
"I think he's going to have WKU doing real well."
A 6-foot-1, 220-pound runningback/linebacker, Ferby suffered an Achilles injury as a junior that he hopes to overcome as a senior.
"Last year was supposed to be my breakout year," he said. "But when two-a-days got started I had an injury right on a nerve in my right heel, in my Achilles, where I couldn't put pressure on it.
"So I had to sit out 8 games last year. I'm back to 100 percent now, I'm so glad. It was a struggle before, and I'm glad to be back. Hoping to lead us to another championship."
What position does Ferby project at for a school like WKU?
A lot will depend on his changing physique.
"I've been projected as a runningback for a few years," he said. "But I'm up to 220 (pounds) now.
"So I guess you could say I'm moving to an athlete-type position, there's a chance I could play linebacker too."
The Class of 2014 standout is now working on scheduling his visits, and already knows what he's looking for in a college.
"I want to get up to WKU in July," Ferby said. "I'm not 100% sure but I'm going to try, I'm hoping to visit Vanderbilt in July too.
"First of all, academics is one thing I'm looking for. I also want somewhere that I have a good relationship with the coaches, and somewhere I can get some early playing time. I don't want to sit on the bench for very long."
