I have to defend Rogers even if I don't want to. They likely have the LEAST shady accounting in the league, given that they are a publicly traded company. That being said, the Jays are 100% being used as a loss leader, but honestly it would be difficult to quantify exactly how much of a benefit the team is to their other segments. As a guy who spent several years in corporate finance in telecom, I know a 1% change in input variables can change an outcome by $10's of millions. And those impact variables are either educated guesses or taken from some co-worker "expert" who is some 55 year old dude who has worked for the company for 25+ years and cares way more about his pension than anything he's doing (not saying that's the wrong attitude, that's the RIGHT attitude actually - but not conducive to getting accurate numbers).
If all teams were a publicly traded company where the franchise value is proxy for the market cap, I'm definitely buying the A's.
