I disagree. Those clubs would require him to perform miracles to get a sniff of a top job.
Morton, maybe, and it's a big maybe at that, he might get them to the Premiership, but just keeping them up would be a stunning achievement.
Our fingers have been burnt with appointing Goodwin based on getting St Mirren close to the top six and beating some big teams while on a good run. So Robson would probably need to hope a Motherwell or Kilmarnock took a punt on him, maybe a Dundee United if he's lucky, then he would need to be smashing it out of the park with them before being considered by Aberdeen.
That sounds like a very slow, arduous journey where a few bad months and the sack somewhere could see his reputation in tatters. Paul Hartley - once tipped to be a future Aberdeen or Hearts manager - is essentially at a backwater in Cove (I get the oxymoron there) after Dundee didn't go to plan, then Hartlepool after slightly restoring his reputation.
Not only that, but Robson is not going to be learning off Steve Agnew at Morton.
Even if Robson doesn't get the manager's job, he's too highly thought of at Aberdeen to be told U18s is all he's ever going to get. I expect he'll be first team coach at worst, unless we appoint a manager who insists on his own backroom team.
If that happens, wouldn't surprise me to see Robson pitch up as a coach at a big club in England, perhaps if Agnew gets a job and takes him with him.
