I don't either but I question how big of a factor he really is in Pitt's offensive success. I don't recall thinking Canada was some offe dive whiz when he was at Indiana.
As you know, it's always difficult to parse out credit and blame amongst coaches.
While perspective from some of the Pitt folks lurking on the boards would be appreciated, I would imagine that Canada has had nearly free-rein in this year's Pitt offense given Narduzzi's defensive background. Canada also put together some pretty darn effective offenses during his time at NC State from 2013-2015. The 2012 Wisconsin offense wasn't too shabby either, nor the NIU 2011 offense.
Regarding his time at Indiana... there were a lot of injuries and ridiculously young teams from 2004-2010. The Hoeppner/Lynch handoff was also a pretty darn emotional time down there.
