Agree 100% with all the above.
I would think about hiring Will Perry off the Whippets & Flat Caps podcast to anchor Sky's coverage as I like proper broadcasters fronting shows. A southern, middle class voice would also challenge certain assumptions.
Hemmings needs to be pensioned off. Bill Arthur may have to do for now but someone with more passion would be preferable.
I'd then bin off Terry O'Connor and replace him with Brian Carney in the box with Barrie McDermott.
Three in the box is enough but if we have to have four then Phil Clarke should be replaced by a more recent player.
Stuart Cummings actually reduces the credibility of the coverage by frequently coming to a different conclusion than the actual video ref, so he has to go too.
Angela Powers should be replaced by Jenna Brooks and we should see more of her as a touchline reporter.
Jon Wells to continue his excellent studio analysis.
