Nathan KinkeadHi Thomas. Glad to hear you want to give it another go. A lot of people left back then when some major repos and add-ons were going down. That actually made the Kodi experience all the better because we didn’t have just one add-on that everybody was using. People spread out and we had a lot less of the congestion problems like back then.
Anyway, about your question about watching NFL, there were several add-ons that I would have recommended you checked out. Unfortunately, it might just be bad timing, but there were a few repos that all went down just a couple weeks ago, so most of those best options are not available anymore.
There are still a couple that might work for you. You can go 2 possible routes… a sports add-on or a live TV add-on.
Here are some pages to check out…
