"I am starting to narrow it down a little," Helm said. "The teams I am really favoring right now are Michigan, Tennessee, Ole Miss and Florida. That list could change [but] that's who I am favoring right now.
"Originally I was hoping to take official visits, now I am realizing positions fill up and sometimes the scholarship you may want might not be there. So, I am pretty confident I will make a decision before the season, but I'm not sure when."
The 6-foot-5, 220-pound Helm has already visited each of his four favorite schools, and made a return trip to see one this past weekend.
"This past weekend I went to Ohio State and Michigan," Helm said. "I was at Columbus on Friday and watched them practice, then went to Ann Arbor on Saturday.
Ohio State is one school that Helm has not yet received an offer from, and this was his first visit to their campus.
Michigan has offered Helm and his visit to their campus on Saturday coincided with the Wolverine's spring game.
"I took my dad up there because he wasn't able to see it the first time around," Helm said. "It was more for my dad's sake, but it was good for me to."
