Pretty effective ad. Short. Snappy. To the point. Takes a shot at your biggest rivals. Celtics fans have to be a little more giddy after seeing that. But honestly, after the lockout, fans would get hyped over anything promoting the season. The Celtics’ marketing department could have slapped together a bunch of old clips of Antoine Walker, Walter McCarty and Vitaly Potapenko trolling up and down the court and it would have had the same effect.
