The minute I heard the claim that "every play is reviewed in college football" years back I was instantly positive that college football replay was going to be a gigantic screw job compared to NFL replay which actually works.
Definitely a flawed system that needs work.
I have reservations about NFL replay, but it has improved since the early years of under-the-hood-for-eternity. CFB review process is intrusive to game-flow, and results are inconsistent -- time spent on reviews outweighs benefit of making an accurate call. (CBB has a similar problem with "go to the monitor" thing, I'll get into that some other time.)
Think about this: What if last night's game was played in the pre-review era? We'd question a few on-field calls, for sure. Would we be scrutinizing it to this extent, even if most of the real-time officiating decisions went the same way, positively or otherwise?
It overshadowed a competitive game with a lot of memorable moments, even thought ISU didn't win.
