Sectionals aren't a big deal in Central Ohio because there are so many of them available. If you look at D-1, there are what, 4 Districts and 8 Sectionals? That's alot. Also, there's not a ton of parody in Central Ohio. Look at D4. Wellington and Grandview Heights were guaranteed to win their first round games by 30+ without breaking a sweat. Over the last 10 years, it's always the same schools (at least until competitive balance came) who make it. Granted, there are some exceptions, but it's not seen as much of an accomplishment because there is so little balance.
But it's not like that everywhere (mostly rural areas). Take the Mansfield/Madison District for Division 2. A 21-1 Upper Sandusky team squeaked by Mansfield Senior by a score of 62-61 on a neutral court for a Sectional title. That's a pretty solid accomplishment worthy of celebrating. Ontario is a school that wins 15+ games every year, but only has a couple of recent Sectional titles to show for it. They just knocked off Lexington, a team that made it to state a couple years ago, in the Sectional Finals. Isn't that worth celebrating when there's only 1 District champion within a 50 mile radius?
Another example: Delaware Christian has never won a Sectional title. Shouldn't they be able to celebrate it if they had won this year? They certainly couldn't win a District title against Wellington or Grandview. They had no chance and everyone knew it. Heck, nobody has a chance of winning a district in D4 Central this year except Wellington or Grandview. Can't they play for something? If East Knox had won one for the first time in 20+ years, shouldn’t they be allowed to celebrate? I say give them the option based on history and expectations. Not everyone is like Worthington Christian, Africentric, or Harvest Prep and has a chance to win a District every year.
So all that to say I totally see your point, especially if you've been in Central District your basketball life. Winning the MSL Ohio is a bigger accomplishment than winning a Sectional Title. But in many rural areas or smaller schools, it's a big deal worth bragging about IMO, especially for those schools in which it rarely happens.
