A TON of injuries this year. Something like 102 players have played at least a snap this year. That is absolutely amazing that they've been able to remain undefeated with all that and really speaks to their depth. I don't know how healthy they will be coming out of their final bye week this last week and what they'll have for the final month of the schedule, but if they've really been that dinged up, it will be interesting to see how they continue holding up through this next month of November.
Also goes to show that other teams can't use numerous injuries as much of an excuse anymore. It also says something of ISU's coaching staff.
