Again, that's about the exit strategy...not about the JUCOs. If you recruit only HS kids and you quit, you'll be in a bad spot the following year.
I'm not advocating one thing or another and I'm certainly not complaining about Skip. I'm just saying that the issue with Sonny was that he quit, not that he was recruiting JUCOs. We'll find out soon whether or not Holtz has as good an eye for talent as Sonny had.
