Davie Weir fucked up once in management. Most successful managers fuck up at a club in their careers. He has a better track record at being an Assistant Manager so if he arrives, what's th eproblem? As for taking on Cathro - it's a chance, but why not? Walter Smith was promoted from Assistant to Manager; sometimes it works brilliantly, sometimes it doesn't. Warburton would be a better choice overall though - he will know more players and the level of transfer market we are looking at.
