Sure, they could have taken him to the Coca-Cola Museum or the aquarium. But seeing as how Tucker is a high major basketball recruit, that field trip wouldn't be nearly as relevant to his interests / aspirations as a trip to the TNT NBA home studio that he probably watches on TV numerous times a week probably is.
Nor would the Coca-Cola Museum help fuel the narrative about distinguishing how cool and hip Atlanta is for a high major recruit on the basketball scene compared to other, less cosmopolitan locales that have stuff like aquariums that kids like Tucker probably aren't all that interested in. Pastner is selling him on the advantages of being in Atlanta, because that's what they have to sell. Just like I'm sure that Syracuse is selling him on tradition, the Dome, and playing for a hall of fame coach, because those are the advantages that our program has over Georgia Tech's.
Who cares whether he sets foot in that studio again, or whether the only time he ever sees it again is when he's watching NBA halftime shows on TNT? Does anyone think or has anyone suggested that Tucker is going to base his decision on how often he's going to hang out in the TNT NBA studio while he's in college? It's just part of the experience the GT staff is selling him on how cool, urban, and happening the city of Atlanta is.
Honestly, not sure what is so difficult about this for people to understand.
