Bro when I was at UM I worked in the BUC in operations. I would help lay down and pick up the basketball floor amongst other things. We constantly had to chase Jack out of the arena. The floor takes a few hours to pull up, it basically comes up in rows, each piece is prob 4x8 and you have one guy pulling the pins out of the floor and four guys lifting and staking row after row if that makes sense then you wheel them all to the back.
No joke one time Jack was there and we were pulling up the floor and we picked up everything around him until there was only one strip left and he was practicing his stepback on that one strip of floor that was still down. Dude was dedicated.
