I think there were 3 maybe 4 what I would call gimmick plays. All of them were executed quite poorly. Lack of practice? Player concentration/lack of desire?
I will say one positive about Sonny's Mustang teams - they usually ran one gimmick play against TCU with great success.
TCUs athleticism was likely the best we have seen since 2018. So certainly that influenced the success/failure of those plays. The reverse pass by Austin was crazy bad. As others had mentioned, he could of run for it, run more and then tossed it, even take a beat to plant and then throw accurately. I know he is a WR and does not throw a pass often, but wow.
