Honestly, IDK. A million bucks a year with incentives is much more than anyone else in the CFL makes. Is that kind of money insufficient, especially wrapped around a rare job in pro sports? I'd be ok with a high cap on bonuses for that role. If they generate sustainable growth, they should have their salary grow. I don't want to incentivize a commish to come in, pump up a bunch of trash expansion teams and some front-loaded sponsorship deals, and then bail after getting paid.
To put it into some sort of comparison, the company I work for had a net income under 400m (all USD numbers) last year. His base salary plus performance bonus hit under 3m, though he received considerable stock extra for an exceptional year (everyone's bonus was a record high). This is a big company, if you scaled his rate of earning in a record year down to CFL revenue levels, the commish would make pennies. For further comparison, Bettman made under 10m, and the MLS commish got under 5m and he's seen insane revenue growth in his time.
