re: Will someone explain to me why Tom Herman is such a hot commodity, I don't get i

Blowout wins against good P5 teams suggest a very high ceiling and he is relatively young. If he pans out, you could be set for the next 20 years.

Of course, you've got to weigh that against the losses to inferior teams. The question is which if either would follow him to a program with top tier talent. Will he dominate, or will he continue to inexplicably shait the bed in some games? That question simply can't be answered until he gets a job.
