If you have an account with one of the major cable companies and you have a package that includes at least the first tier of ESPN channels and you have the ability to access TV on line, then the process if you have set up a user name and password to sign into cable TV.
Go to the ACC.com and select Miami as the school ( or another school if you are testing). It will display all the current events and, where appropriate, will display a WATCH spot.
Click on the WATCH link. The first time you do this, it will ask you which Cable company you want toe use. Most of the majors are listed. I have Comcast. You will get a sign in page where you log in as if you were logging in to view something else on your cable.
It should send you to the event and you start it like any other video. If you have a browser on your phone, I'm old and have one, you do the same thing.
If you are comfortable with apps, follow the guidance of those on here more knowledgeable than I.
