I mean it clear we just disagree here. My guess if he played for the Bears you wouldn't be making this case.
The rules are no gambling.
The rules extend to all team activities, why because it's a high profile job and any gambling risks the integrity of the game either by directly betting on the sport or by creating a slippery slope that makes it easier to do so.
I have no problem with the suspension because he knew the rules and violated them. You are just looking for every way to rationalize it away.
