There are some pretty damning quotations from Charlie regarding Riley and his staff's coaching ability:
9:28: McBride asks Riley why the scout team defensive players weren't actively trying to strip the ball from the offensive players during practice. Riley's reply was "I'll have to look into that" :facepalm:
10:15: McBride asks Cavanaugh why he only played five offensive linemen during games: "Because I only get five guys ready to play" says Cavanaugh, which McBride links to the Pro mentality of coaching
There's other gems in here as well, like the lack of time in the practice schedule for individual work/fundamentals work (literally zero time according to what Parella told McBride) and the staff wasn't used to coaching 100+ players (the point that Riley routinely did not have a full compliment of 85 scholarship players at Oregon State also came up, but I'm not sure if that's valid...)
All in all, seems like the past three years were a waste of time, resources, and (most importantly) these kids' ability.
