Mix Arizona and Atlanta up once, shame on you. Mix Arizona and Atlanta up twice and ... you know what, just get out. You're done here. You can hit the showers for the rest of the night.

Well, this was just horrible. Again, the same ref stumbled and bumbled through a challenge explanation. And again he mixed up Arizona and Atlanta. At least this time he caught himself, I guess.

In all seriousness, this whole replacement ref thing is horrible. Sure, this is probably a minor slip. But it's embarrassing. And as refs fumble around, stumble through calls and just plain make the wrong calls, patience is growing thin.

If we have to go through this during the regular season, there's going to be problems. Preseason ref issues? Whatever, maybe they're working out some of the issues. But considering the start many of these replacement refs are off to, things aren't looking so good right now.
