That sounds way higher than it ought to be, but yeah using youtube TV for sports is very expensive. NFL+ is your best bet at 16 a month, but it wont have season opener, MNF, TNF, or SNF. To get all those you need Prime, Peacock, and ESPN. Lets say 16 X 4 = 64 bucks a month. So, 256 bucks a year to cover all the bases.
Last year I had NFL+ for redzone, Prime (not that I TNF games are often worth watching) and peacock at a reduced price of 25 bucks for entire NFL season. So, I came in at 145 bucks for the NFL season. If I had wanted ESPN+ it would have taken me up to 256.
