"It’s not just completion percentage, not just number of interceptions thrown or how many sacks they might take."
Well that clears that up. So completion %, number of interceptions and sacks taken are important but as HCRE2.0 says in the sentence before so are: " How do they command a huddle, how do they command the operation of the offense? " Yeah, give me command of the huddle over completion % any day. Guess that is how Bones earned so many starts @ QB back in the day.
