If you have Hulu Live TV you’ll be able to watch ESPN. I’m not sure it will be available on either the regular Hulu app or the ESPN app.
I believe that you can only access the ESPN app if your tv (streaming) provider (Hulu in this case) carries the main ESPN channels.
A few seasons ago, YouTube TV dropped ESPN for about a weekend due to contract renewal problems. It was during the college basketball season, maybe even in March, and I was not able to use the ESPN App on my Roku or Firestick. (We switched to Hulu Live immediately and never switched back.)
Maybe this policy has been changed by Disney/ESPN but I don't really know for sure.
@cferraro04 what's your plan for watching the Big Dance without access to ESPN?
If you don’t have Hulu Live currently, check their website and see if you can get a free trial of it, usually good for 3 or 7 days.
