A few quotes of interest from that article, as it managed to open in Reader mode for me without subscribing! - We can reveal big names such as Vernon Kay and Sara Cox have ruled themselves out already – with BBC R2’s overnight presenter OJ Borg being seen as a front-runner in the race. - A source said “Meanwhile, with Greg James, he is Radio One’s biggest star and it would be too big a risk to move him onto Radio Two’s breakfast show right now. They need Greg to steady the ship on R1 after the shock of Scott’s departure from the other station. Everyone has been hit really hard by what’s happened.“ - But our insiders say Sara has no interest in taking over the early morning slot. “Sara has been there and done that. She always enjoys covering the breakfast show from time to time, but she’s not currently interested in taking it on permanently.  

They're just quoting the same Sun article.

Daily Mail now also reporting Vernon and Sara have ruled themselves out of taking over Breakfast 

Would make sense though as does a sort of quiz I think midnight mastermind so could do that sort of thing on breakfast 

OJ and his family are also based in Manchester, which is why the overnight slot works well for him. I just can't see it personally. The Sun are known to create fake 'insider' stories so i'd take it with a pinch of salt.

Can you elaborate if possible can't be bothered to subscribe lol

Based on what I read I don’t think it will be Sara Cox

Sara was talking about women getting promotions in work places and should be proud of strong women earlier on 👀

…a “wild card”, as one insider put it. It could be proven to be wrong but that’s what I always thought. It will be someone you don’t expect 

I’ve read it, basically it won’t be Sara Cox or Vernon Kay. It will be an outsider like OJ Borg, someone who isn’t a household name 

Can't read the article its subscription only

Sara Cox and Vernon Kay are NOT interested in taking over the Radio 2 Breakfast Show. Insiders suggest the BBC are looking to pick a “wildcard”, someone who isn’t too big of a star but will offer long term dependability. I said this before, it will be someone you don’t expect. Could it be OJ Borg?

And that is no reflection on Scott as a professional, it's just an element of radio he wouldn't have delved into for some years. Specially since 1998 being at the BBC as they have teams doing all that background work for the shows and the presenter literally turns up and does a show. Even when I am voice tracking for Stations via software like Myriad anywhere or Playoutone Web VT, you still have to make changes, like adding music to the hour as it is short, and making sure everything flows, and the right songs are next to the right songs, for example if I have a song > sweeper > song > link > song and the song after the sweeper has a 30 sec intro but the song I am linking into doesn't I will swap the order about so I can use the one with the intro to talk into. At the BBC the producers will sort that kind of detail as the show runs. 

With Apps like Radio.co or citrus it is pretty easy to set one up these days to run in the cloud and upload music and jingles to it to rotate and then take it over live if you wanted to. I help run a station on radio.co which runs on music and jingles and pre recorded hour bloks of shows and uses alot of syndicated content as well to fill hours up. I would imagine he has a lot of music already in his storage from when he does DJ sets, but to run a sucessful online station you need a database of thousands of songs, I have over 23K songs on my hard drive at home, of varying genres and still haven't got "everything" but am able to produce 13 shows a week using it but you have to master your software and music rotations, with programmes like musicmaster or music1, which as a presenter on BBC I suspect Scott himself hasn't delved into production or programming for at least 20 years, because those stations will have teams doing it for you, you just come in and play the songs and do the links, where as to run a station you have to be programming, producing and all the rest. It is a never ending job, even for my own database I have to download each track (legally and paid) upload it to the database, categorise it, set the intro, extro and hook, and all that before scheduling the following weeks "logs" aka playlists for each day of the week.
