Except for perhaps the NCAA Top 10-to-15, who in their right mind could survive the workload of being a head college football coach if this trend continues?
You have to re-recruit your entire team every year?
re-recruit your current players...
recruit high schoolers...
recruit the Transfer Portal...
retain your staff...
find replacements for departed staff...
Not only is rebuilding a program now virtually impossible but the job responsibilities of the head coach have become, IMHO, literally overwhelming.
