Here's an interesting quote from a VQ War Room update from roughly the same time in fall camp last year:
Clearly Butch has changed some things around to keep guys healthier, because there has been no talk whatsoever by the VQ guys or the 247 guys about the team looking beat up. A few dinged up players here and there, sure, but very few guys missing multiple practices or extended camp time.
Also, here's a list of the players who were indicated as being some level of "injured" in the final three War Rooms before the BGSU game:
-Gaulden
-Perry
-Croom
-Josh Smith
-Jack Jones
-Wiesman
-McNeil
-Marcus Jackson
-Kelly Jr (recovering from tonsil surgery)
-Martin
-Sanders
Obviously not all of those guys were lost for the season, but their injuries were serious enough that they missed practice time. Also, Danny O'Brien was suspended for a few games early last year.
