1) Re the OP: Late hit on ISU - horrible call. QB was IN BOUNDS when contact occurred, after a juke to the inside! You simply can't flag that. No idea why the announcers were acting like it was an easy call.
Other notable calls:
2) Unsportsmanlike conduct on Tucker - he taunted, good call. OTOH, I've seen worse not get called, and if this gets a pass Tucker is on the field more and we might get an extra stop.
3) Unsportsmanlike conduct on BU's OL - he taunted a little, good make up call. If you don't call Tucker's, you have to let this go.
4) Overturned Fumble at half time - bad call. I know many disagree, but if you watch closely you'll see that the QB only had his fingertips on the ball prior to it crossing the goal line. In other words, the ball was already loose and the call should not have been reversed. This one would have been the difference, but it wasn't a blatantly bad call.
5) Lazard's personal foul - IMO a bad call, but close enough not to complain. At least he didn't get tossed.
6) Missed facemask on Linwood - How did they miss that??? Horrible missed call, but in the end didn't hurt BU because they scored anyway.
7) Phantom hold on Bobek - horrible call. He reaches out to touch the DL with the play already downfield? Are you kidding me? Can't remember if this hurt ISU. Was that a series when we scored anyway?
Did I leave any out?
Disclaimer - of course ISU could have won anyway, and every team gets bad calls.
