So MSU intercepted a Nebraska pass in overtime, first possession. They did not score on the runback so that ended Nebraska’s possession and MSU got their possession on the 25. However, there had been a flag on Nebraska during the runback which got me wondering - what if that penalty had been on MSU, say, an illegal block. How would that be assessed? Usually it is 10 yards from the spot of the foul but how could that be done in this situation? Would it be enforced on MSU’s possession so they would start from the 35 instead of the 25? I wouldn’t think it could just be ignored otherwise the intercepting team would effectively be free to foul during the runback. Unusual situation but I can’t imagine it has not happened sometime.
