Was at the game last night and my kid says, this place really is a dump and I can see why people want a new arena.
To get to our seats we had to twice turn around and go back down and up the other side of the stairs because there was a dead end and not complete access. Not sure how, with the skinny footprint, they would be able to modernize the facility with enough seats inside the shell. Maybe lower the floor and have top load seating light 3M arena, but not sure how you'd fit in a quality concourse or any luxury seating.
Lou Nanne was on KFAN and said that basketball deserves a new facility and would build right in the same location, playing at Target Center and/or Xcel (even a split to draw fans from the east and west). He also makes a good point that often after remodels there is regret that they should have just built new.
I just don't see the consultant coming back with a viable option to remodel without going significantly under 10,000 seats.
