To be 100% honest, I don't remember comparing Harris or any of our former QBs to any of the greats. This includes Dorsey.
None of them really inspired the comparison for me, even on their best days.
What TVD has done the past few games is a breath of fresh air. He has shown FLASHES of greatness. Doesn't mean he will be great going forward, but it has been fun to watch. And it's brought back (a little, much needed) hope to The U. Nothing wrong with that.
Edit: I've been watching Canes football since 1991, FWIW.
