There a lot of logic to this move.
To have Coady and Basham in the squad means we could do away with pursuing both Lehihan and Leonard.
One less player to accommodate and keep happy, plus you are not asking one player to shake off relegation and be better and the other to step up. You would have a bona fide Championship performer.
The move might make sense for him too. The direction Wolves are going, with Mendes so heavily involved and foreign coaches does not necessarily lend itself to longevity for Coady there, regardless of whether he's done ok filling in at centre back for them.
Let's see where it goes, but Wilder doesn't seem the type to waste his own time. And Agents talk. There must have been an inkling there was some appetite for this to happen, from player or club, or it would not have got to the point of placing a bid.
