Not many actually. So let's take a sport by sport look at whether Dover would be the instant favorite. This is based on how things have gone since the IVC was expanded in 2016-2017.
Football - Yes, of course.
Volleyball - Never
Boys' Cross Country - No
Girls' Cross Country - No
Boys' Golf - No
Girls' Golf - No
Soccer - IVC doesn't have soccer
Tennis - IVC doesn't have tennis
Boys' Basketball - Yes, but definitely years teams would compete and challenge them
Girls' Basketball - No. Not a chance
Wrestling - No idea. Can't tell you a thing about wrestling
Bowling - IVC doesn't have bowling
Baseball - Probably the favorite but certainly not unbeatable
Softball - They'd avoid Strasburg so they'd be in the mix for sure but not auto favorite
Boys' Track - No
Girls' Track - Probably. Dover and TV have been battling it out in meets for a couple of years now with each winning some.
I'm sure Dover would finish in the top half of the league in pretty much everything but the IVC has some really, really strong programs at the top of almost every sport that Dover isn't beating right now.
