Well regardless of who has more inherent advantages, we can still be those schools. It's only been in the last five years or so that we distinctly passed GT as a football program in the time I've been following college football.
At the end of the day, I don't see Narduzzi as any better or worse than Fuente, Hafley, Collins, etc. He's kind of in the the "Average Joe but he's our Average Joe" category. Those guys may catch breaks and stick around for a while of they may get fired after a handful of years. But I don't want to start over in the portal era. You'll lose half your roster, and once you're down there is no guarantee you'll get back up off the mat for a long time.
So what if we lose half our roster? That could be a good thing. Guys like Bartholomew are transferring anyway. Who on this roster is better than any random dude in the portal we can get.
