there are worse things to worry about than, during a period where we can't go to games, being able to turn the tv on pretty much at any point during the weekend and see a live match.
even though its an unpopular view, the revenues of sky and bt have taken a battering during covid, either through churn to other broadband providers (when sport was off) or loss of ad revenue, which although a much lower % of their model than say itv, is still enough to cause redundancies and importantly inability to physically make or fund other decent non live programming (have you seen the shit on recently?).
hence, maximising the number of games shown live by spreading them out.
it works both for the clubs, stations, fans and ultimately the gov who want people happy at home after their socially distanced shop and socialise with 6 or less.
added to that, channel 4 (publicly funded) actually sell BT Sport ad inventory for them. They lost 40% of their revenue during covid and are as ****ed as itv, so I can fully understand and support why they want to show games 1 after the other.
The quid pro quo is that they release more free to air - which means i get to paint the shed, play with the kids, eat sunday lunch and still settle down to watch City before watching McIlroy win the US Open.
