You can potentially distill coaching into two things: building a team that produces great stats and figuring out how to maneuver in tight games when neither team has a statistical advantage. The former matters above all (Nick Saban and Steve Kragthorpe, after all, are nearly even on this list ... and on no other list in existence), but if nothing else, this list might help us to understand which teams/coaches are good or bad at the latter.
I am interpreting Connelly's maneuvering quote as "game management." His list goes starts at 2005 and captures coaches with four or more years as a head coach. Of note:
-- TOB: Diff/Wins per year = 0.66; Percentile among coaches = 93.8%
-- Spaz: Diff/Wins per year = -0.01; Percentile among coaches = 52.8%
-- Addazio: Diff/Wins per year = -0.41; Percentile among coaches = 20.6%
A few notes of clarification. Since they started tracking in 2005, most of TOB's data is from NC State. (I can't speak to how he managed games there.) It also includes Addazio's time at Temple. It also doesn't factor in the huge issue of talent and recruiting. By this simple measurement Spaz is a better coach than Addazio, however, Spaz's mismanagement of multiple aspects of the program left him winning fewer games each year. I also don't think TOB is some sort of Bill Walsh genius who was never appreciated. I think he was ultra conservative and rarely beat himself, but also never took risks when he had to (at least at BC).
Does this mean Addazio can't improve or can't win big? No. Talent overwhelms at a certain point (see Nick Saban). But I do think it validates us when we are scratching our heads at some of Addazio's decisions. I also worry about Addazio's sounding boards in-game. Who will replace Pasqualoni as the voice in his ear about adjustments and decisions? (It should be noted that Pasqualoni's numbers are close to Addazio's.) I just hope the coach is doing something to adapt, so this factor starts breaking BC's way.
