This has been clear since Dundee United knocked us out the cup. There is no way Danny will be getting a new contract to manage here next season, regardless of what happens between now and May. He's wasted far too much money on transfer disasters and oh, we are in the ever familiar position of 11th in the league.
Danny therefore is not managing us between now and May to win a contract at St Mirren, he and the BoD knows that won't be happening. Danny's motivation in managing us between now and May must be for his future employment possibilities.
If Danny relegates us it is pretty likely he will never manage a full time club again. Look how long Gus took us to get back in, and he had achieved more with us than Danny has. If he keeps us up he has a decent chance of getting a job with a Championship or a League 1 club like Morton next season.
