If we want to bring in former NFL players because we think NFL players make good coaches, let's bring players who have had more success in the NFL than Sage and Seneca. They don't have to be Iowa State alumni.
Sage and Seneca mean infinitely more to the fan base than they do to any recruit. I'll bet half the student section at games this year couldn't pick either out of a line-up...much like I wouldn't recognize players from the 80s when i was in college in late 90s.
Not saying they couldn't do the job, just saying this search should involve critical thinking...not following our hearts based on fond memories of past players.
