Kiel, a Columbus, Ind., native, was originally committed to Indiana but decided to reopen his process in late October.
Kiel visited Notre Dame for its game against USC, and then took in an unofficial trip to Vanderbilt earlier this week. He was joined in Baton Rouge by his mother and father, though the family elected to pay their way to Baton Rouge and save Gunner's official visit for later in his recruitment process.
Hill was set to sign with the Tigers in 2011, but legal trouble off the field forced the then senior to finish the year out being home-schooled.
LSU expects to bring Hill back into the fold for the 2012 class, and the Baton Rouge native could arrive to campus as early as January.
Brown worked out at LSU's camp this summer, and he has maintained contact with members of the staff since.
The 6-foot, 175-pound sophomore has gone on record that the Tigers are a team to beat for his services in two seasons.
