Again, I offered my thoughts, but I can reiterate. 1) I cannot tell if the ISU player who goes to the ground along with the IOWA player is grasping the IOWA player or not. This could be a true hold or it may be due to the DL being taken to the ground. I have watched both angles and cannot tell. 2) Yes, if the holding hadn’t happened, ISU could have run down the clock or they may have fumbled. That is not an unreasonable assumption given the prior results. 3) What are the chances that the kicker makes it?
If you run through all of these variables, the likelihood of the result that you desire continues to decrease. I don’t live in a world of hypotheticals. None happened. What did happen is ISU got a re-do on 4th down and your QB threw it to an IOWA player. IOWA then relinquished possession and ISU fumbled.
The refs did not cost you this game. Go win your next one and find peace with reality.
