i literally am looking at lumen field and tmobile right now, so I can provide pretty good first hand accountsThe Sonics are not and would not be more popular than the Seahawks. Which doesn't nullify that Seattle is obviously a basketball city. But all those Seattleites in that thread say Seahawks are #1 and there is no close second in Seattle, even if the Sonics come back.
People probably need to come to grips with the likelihood they may never get a team again.
Seahawks are the most popular. The Mariners WHEN HOT are actually a close second. That thread is over 2 years old. This year's mariners run was on par with peak LOB fandom. It was. The sonics aren't even a subject in that thread. If the sonics came back in YEAR ONE, they would be the hottest team and ticket in the city. Whether that wave stays for them to be above the hawks, i don't know but it would depend on success. I wouldn't expect that after year one though just because in every city with an NBA and NFL team, the NFL team is #1 other than NYC, LA, and maybe Boston arguably.
