I'm sure they have lots of information on him, his tatical adaptation, formations, style etc when he's never been a head coach before.
On the contrary he may be our Kieron Mckenna.
Speakman probably knows more about Dodds, and his philosophy, than any other possible candidate.
The club will also know how he interacts with the players, who praised him highly after the West Brom and Leeds games.
And, ever more important, will have a good working and personal relationship with Speakman.
