I had a problem with the chains thing myself. This likely doesn't happen in the NFL (before the 2-min warning, anyway) since the coaches will likey be all over a bad spot with their red flag. Bottom line is that these calls are physically NOT reviewable after the chains are moved, so if it looks close, it should be reviewed BEFORE the chains are moved.
Other than that, the Hens had a shot afterward and failed to make good on it. Besides, most Delaware fans aren't the ones who are vocal about the chain call. It's disgruntled NDSU fans who are STILL seething over supposed injustices perpetrated by the officials during the game in Cheney.
