Way too long in between Semis and Final and to play on Sunday at 2:00 eastern on the final week of NFL is just ridiculous. Playing in a soccer stadium isn't ideal either. It's a shame for those programs.
The non D1-A levels are dominated by the programs that don't have quality local programs from the next level up. Exceptions to every rule, but the below is generally true.
D1-AA: Teams that win regularly do not have quality D1-A programs in their general area. Exception to this could be JMU when they were D1-AA, but VA Tech and VA haven't been consistently good in years.
D2: Teams that win regularly do not have quality D1-AA programs in their general area. D2 final wasn't close, but it was fun watching a complex running offense win the championship. Love option teams.
D3: Teams that win regularly do not have quality D2 programs in their general area. D3 final was an absolute nailbiter ending in an upset of the #1 squad and recent dominant program.
