Leagues are "forward thinking" for completely shutting out casual fans these days.
It's getting a bit crazy with the praise for being "the first" league to sell their rights to a streaming service. As if they invented some new concept. Small college conferences that weren't on TV were doing this in 2007! -- I paid ridiculous prices to stream games of my friend who was playing in the Big Sky Conference which I had to buy the entire conference set of games, and paid even more ridiculous prices to watch my other friend who was playing D3 football -- Or like when the entire Major League Lacrosse regular season was exclusively streaming and only the ASG and playoffs were on TV. Tons of niche sports, and leagues/conferences have done this before and some were doing it over a decade and a half ago. MLS didn't invent having their games available via streaming.
Plus, if this was the genius idea as it's portrayed by some, leagues that are much better run (business wise) would have already been doing it. Obviously. Actual "major leagues" (MLS isn't in the Big 4 and isn't really even close to the Big 4, the bottom being the NHL which MLS isn't half of if we're being honest) ... There's a reason why the NFL and NBA weren't the so-called 'leaders' on this type of deal and there's a reason why MLS "had to" do this type of deal -- essentially forced as opposed to doing the deal as some sort of "forward thinking" stroke of genius that was also done out of the goodness of their hearts for their cord-cutter fans. That doesn't even make sense.
Also, casual fans matter. I was going to Sounders games when they were in the A-League with 1,000 people in attendance. That didn't jump to 30k because of "word of mouth" or even just because of the jump up to MLS. The move up was 'new' and the Sounders became the hipster thing to do. Portland isn't too different there, hipster culture more than grassroots supporters of an independent club. It's a single-entity league after all and soccer in both markets existed well before MLS came along.
And it has always mattered for the Sounders popularity that all their non-National broadcast games were OTA here. I know tons of people who didn't start watching the Sounders because it was some underground thing that only the cool kids knew about and they were invited by the secret society members to join the club. No, they started watching because the Sounders were on Channel 5 & Ch. 16 and then Channel 13 & Ch. 22. OTA, free. Then they eventually started going to matches. Bought merchandise, jersey's, etc.
We won't know until it starts to play out how it'll all work out, but I do know it's not the greatest sports business decision in World history, so we should at least discuss it with that in mind.
