While we're talking about bad calls, what was Tucker's unsportsmanlike for? It looked like he just got up celebrating, didn't look like taunting.
Tucker's call was as easy as the calls on the guys earlier in the game for clapping in the opponent's face. He gave the two handed get up motion in Russell's face as he stood up from making the tackle. Unnecessary and he got to spend some time thinking about it on the sidelines.
Lazard's and Cotton-Moya's late hits were garbage. That said, there was also one missed on one of the final drives in front of the Baylor bench and an obvious facemask on the long Baylor run that they reviewed on the last drive of the first half.
In the end, ISU's inability to score in the 4th quarter is part of the needed culture change. That far precedes Campbell and staff. Baylor, despite how bad they look defensively, is really good at making adjustments on defense. They still have not given up a 4th quarter point through 5 games, many of which included significant playing time by backups. Those two items are a great representation of the difference between teams that are accustomed to winning and teams that are not.
