Mark McIntosh was running out of time. It was summer 2024, and the former Denver sportscaster, who spent 18 years calling games and interviewing athletes on KCNC (Channel 4), was living with amyloidosis, a rare disease where misshapen clumps of protein build up in your organs. Chemotherapy kept it at bay, but the condition destroyed his kidneys, and he needed dialysis to stay alive. “I was chained to a machine for four hours at a time, three days a week,” he recalls.
