My take on it is this. One of the provisos of the CBS paying to have their name on the arena was that Cov had to playing there. If he kicks them out, then CBS will drop the deal and Ashley can call the place what he likes, the Massive Mug Arena maybe.
Sky Blues will be desperate for somewhere to play, so Ashley will try to get a deal on improved terms, the rent was cheap under Wasps (probably the main reason for evicting them). Job done. He'll then be hoping that SISU will agree through clenched teeth and he can then buy what's left of the club for a song. Stumbling block for that part of the plan could be local businessman, Doug King owning the lion's share. Unless, he's in on it all, of course.
