That is a great point. Here is a statement from a Ga Southern site about the option attack. I think it applies to IU.
"Okay, now that we’ve got that out of the way, why
should we run the option? Glad you asked.
Another contradiction in Wolken’s tweet is that his premise works both ways. It limits your “pool” (although
you’re only hiring one person) but also limits the number of schools willing to hire your coach away. Georgia Tech may very well have lost
Paul Johnson after winning the Orange Bowl a few years back if he ran some more PR-friendly scheme.
Granted, that hasn’t stopped the revolving door for successful Southern coaches of late, but it can’t hurt.
I’ve been hearing for at least the last 15 years the option is outdated, and yet as I write this Army is 6-2, Navy is 5-2 and Georgia Tech is 4-2. Somebody needs to tell them they’re not allowed to win with those old-school schemes.
The biggest reason of all to hire an option coach is identity. The Triple Option IS Georgia Southern’s identity, known across the country among discerning college football fans. At this level of football you need to have something to hang your hat on or risk becoming part of the interchangeable list of random mid-majors. There’s no good reason to trade in that history and tradition.
Beyond that, the option provides real, major advantages in recruiting. You don’t need to compete with Georgia, Auburn, South Carolina or any other of the nearby big-timers for talent,
since the option requires shorter, smaller, faster players from the offensive line all the way to the quarterback."
The last italics is mine.
