Downtown Pittsburgh has plenty of capacity to handle the requirement the League office requires. Plus, peripheral areas around the city will have room. I think the minimum is 400k capacity for rooms for the draft. I went to the 2019 draft in Nashville and it was fantastic all three days. Blew away all attendance records at the time. Nashville just closed four downtown city blocks right there across from the river. Centerstage on Broadway, with all the clubs and cafe’s in those blocks within walking distance and most had live music when the draft wasn’t going on. My brother enjoyed it immensely too and he has been to a SB at Jerry’s World. Nowhere near the volume of people than at the SB and SB week, but that experience was different. Only two teams fan base were there (at least true football fans, most of it is corporate fodder.
Having all 32 teams fanbases in a host city was unique and for the most part the majority of fans were “respectful”. However, my group got into it with some Philly fans and my son and I had some Stain fans claiming they were going to own us. Their typical modus operandi.
I‘d would love to go again, especially in the Burgh. I’ve got family there so hotel reservations wouldn’t be needed this time. It is expensive, as there are all kinds of vendors there. Having stage at Point Park maybe? IDK, downtown isn’t a perfect grid like Nashville.
