There have been no quotes from anyone involved in the articles linking Broadfoot with moves to the Old Firm, so quite how true they are is hard to say. If Broadfoot did move on a Bosman, Saints would be entitled to some compensation as he is under 24. However, this money would have to be split with former side Hibs.
It's debatable whether Kirk is good enough to play for the Old Firm, as his performances this season have been a bit dodgy at times. However, the improved coaching and facilities on offer were he to move may help him in the long run.
This story suggests the chances of Broadfoot playing for Saints next season are increasingly slim, and wherever he'll goes he'll probably end up on far more money than he could ever earn at Love Street.
