I don't do frame by frame Zapruder searches for blown calls like you guys. Maybe you could hire someone like Mueller to look into this after he is done with Trump.
Refs have cost us games vs Nebraska and Ohio State. But I don't believe that was due to "bias". Refs are human and can have a bad day. If you want to still be upset about a ref call from 2005, hey, whatever makes you happy.
We don't have to do Zapruder searches either since there are examples all over the place. You can't swing a dead cat without hitting one.
