It appears Sam Keller is officially a Husker. Reports are Bill Callahan confirmed after practice Wednesday that Keller is joining the program. He'll be eligible to play in 2007. No doubt Callahan feels like Christmas came early this year. Keller is a proven quarterback, something the Huskers would have been missing next year after Zac Taylor graduates. He was also supposed to be one of the top senior QBs in the nation this season before his problems at Arizona State. Keller still will have to compete for the starting job, but you have to think he'll be the No. 1 candidate to replace Taylor when spring practice begins.
