Can Someone Help Me With Buying Nba Jerseys?

Hello!
I’m kinda confused. I have never bought a basketball jersey, and I wanted to buy a Drazen Petrovic jersey, since he’s my idol. So I went on amazon, and they had two different jerseys, a Swingman for 90 dollars, and a throwback for 55, so I went for the throwback for 55. Is this a good deal? Is there any chance that this jersey is a fake? It says that all the letters and numbers are stitched. When I watch videos on youtube, all the throwback jerseys are either ”Hardwood Classics” or ”Mitchell and Ness”. On amazon, on the swingman it says ”by: adidas”, but on the throwback it says ”by: LYQ”. What is LYQ? Is that the brand? I’m kinda stupid, so I hope someone can help me so I don’t waste my money!
