Do you two think the current laws are adequate to promote healthy sports leagues for our society to enjoy?
Whether or not they are optimal, they are certainly adequate . . . because we do in fact have healthy sports leagues for our society to enjoy.

I do agree with the sentiment that sports leagues are different from other industries when it comes to whether antitrust laws should be applied to them. In fact, I think the case for applying antitrust laws to sports leagues is
stronger than it is for most other industries.
On the whole, I think that the best antidote to anticompetitive collusion is a business environment that fosters free competition. If five gas stations are going to fix their prices at $5 a gallon and they invite me to join them, why wouldn't I tell them to go ahead without me and then set my own price at $4.89 a gallon? (And if I don't do it, somebody else will — maybe a new start-up.) Agreements in restraint of trade, in general, tend to be difficult to enforce, and therefore tend to have rather limited negative effects. Participants will always be tempted to cheat in order to gain market share.
In sports leagues, things are a bit different. If the 31 other NFL teams are going to fix salaries at $100 million per team (
anti-competitive - would not be allowed) and they invite me to join them . . . what can I do? If I go over the cap, the other 31 teams won't play with me and I'll be out of business. Shell can't put Exxon out of business for cutting prices, but the rest of the NFL can put the Redskins out of business for going over the cap. So I think sports leagues are particularly insulated from free competition, and particularly likely to successfully engage in anticompetitive collusion in the absence of antitrust laws.
That's not to say that I think that sports leagues should definitely be subject to antitrust laws. (I don't think a salary cap, for example, is necessarily a bad thing even if it amounts to collusion in restraint of trade.) I just think the case is stronger for sports leagues than it is for other industries. But I'm open to the idea that antitrust laws should be repealed entirely and applied to no industries at all.
