I'm in agreement we should be looking to improve certain aspects of OT, just not a clean rebuild because it isn't worth it. Do you want an iconic stadium or do you want a money grabbing theme park for the entire family? At a certain point you sell you soul because an events space has to account for all events equally, and the football becomes one of the on offer events. The Rolling Stones won't play OT if the MEN or Etihad is better, so you have to put more effort into that aspect than what's necessary for somewhere you predominately play football.
And by improve I mean look at more ways to get marginal gains out of the team, improve the pitch if we can, not build a Michelin star burger joint and a shopping centre next door as part of the 'experience'. We should be looking to expand the stadium, re-do the roof, maybe even rebuild an entire stand if necessary but OT isn't standing still, it has small work done constantly otherwise they would condemn it and shut it down.
