BOISE, Idaho — Boise State men's basketball has added Coby Karl to its coaching staff, head coach Leon Rice announced on Thursday.
"Given Coby's extensive coaching pedigree and lineage, we are incredibly excited to welcome him back home to Boise State," Rice said. "Coby brings immense experience that will be invaluable and beneficial to our coaching staff and program in its entirety. The knowledge and teaching he's gained from George Karl and Phil Jackson, who are legendary, Hall of Fame coaches, has served him well, and we are fortunate to add that wealth of knowledge to our team."

I'm thankful to Coach Rice for welcoming me into the culture he's built, which it's something I deeply respect, and I'm excited to be part of it alongside such a talented staff and group of student-athletes. It feels great to be home."
