Constrained to Afford

Cal O'Brien: I think all constraints are valid. There's a tendency to sort of nose at constraining, and I'm not 100% sure that we should do on this call. You really need to constrain the whole thing if you're going to be successful with it. John McEnroe: It may just be that in a time limited environment that the players don't attend to or attune to some of the information. So sometimes as a form of differential learning, I suppose, I go to an extreme constraint at the other end.
