It does cut it if we're talking about an actual market that has a hope for future long term success. Most teams don't rely on entertainment districts, and most teams are in the downtown core.
I mentioned this in another thread the other day, but every arena built in the last 10 years is part of a mixed use district. That includes Edmonton and Detroit. The two confirmed new arenas in Ottawa and Calgary will be part of mixed use districts. Every new arena proposal on the table right now includes mixed use districts, including in DC. One team's major renovation project includes adding a mixed use district.
From the perspective of all of these teams, just an arena with ticket/concession/parking revenue doesn't cut it anymore.
