Casillas was originally slated to visit Wisconsin this weekend, but that trip has been switched to Dec. 17. It will likely be his final official visit and he expects to have a decision in mind shortly thereafter.
Casillas has additional scholarship offers, but said his four official visit locations are currently his finalists.
This weekend, Casillas will be making his trip along with teammate Andre Dixon, a running back who has committed to Connecticut. Casillas said, however, that Dixon's decision will not affect his own and that Dixon was not pressuring him one way or the other.
Casillas said his greatest concern regarding Illinois' coaching change was whether Ron Zook's regime would continue recruiting him. Illini assistants have kept in touch with Casillas and told him that they are making him a priority in discussions with Zook, whom Illinois recently hired to replace Ron Turner.
Casillas enjoyed his official to Illinois and his much more recent trip to Kentucky. Each visit defied preconceived notions, particularly Kentucky. He had expected a rural environment and was pleasantly surprised to discover Lexington, Ken., and its urban landscape.
Wisconsin and Connecticut have both paid Casillas an in-home visit recently, with offensive coordinator Brian White making the trip for the Badgers.
An outside linebacker at New Brunswick, Casillas is being recruited as an outside linebacker/strong safety by all four finalists.
