My statement related specifically to the supposed intricacies of the rules. I don't think they are as difficult to learn as folks suggest, particularly if it is your job to understand and apply them. Not respecting them, as you say, meaning choosing not to learn them or embrace them (some, indeed, have made that mistake), is different.
I would believe that Reyna understands the rules. That doesn't mean he has made or will make sound personnel decisions or recommendations, to the extent he even has that power. If someone is making poor personnel decisions for us, my guess is that it will not be because the MLS rules are difficult to understand.
