For starters a big team will TUPE over so they will have most of the people on Day 1. The key question is why it is worth it. IMG currently do the nuts and bolts of producing matches. Filming, studio stuff, etc. They are market leaders. The question is even if the PL can do it slightly cheaper in house, so what? What value is there in owning that part of the value chain. It’s not as if they need it to make the programming even if they created Premflix. And it’s not as if they can take their programming expertise and sell to other leagues. So why bother?
Presumably, there is a model in one of the US leagues they want to follow.
