The injuries did seem ill timed with regard to bleeding momentum off of Nebraska, but booing a downed player is still uncool... unless it's a kicker (those guys are always faking and pop up just as soon as a flag is thrown, never seen a truly injured kicker
)
With that in mind, I have noticed this year - in several games - that the medical teams seem to leave a player on the field much longer than they used to instead of quickly assessing and then moving them off the field so play can resume. I understand the need to make sure that moving them doesn't make the injury worse, but in the K-state game for example, they had the injured player on the field for ages, finally moved him off the field on to Nebraska's sideline and only then had the cart drive across the field to get him. It seems like they would have shaved probably 5 minutes or more off of the time from injury to treatment (as well as allowing gameplay to resume more quickly) by calling the cart in before moving him the first time and heading off the field towards the locker room/med center to better treat him.
