Can Boyd and McFadden rejuvenate the SPL?

So James McFadden has returned to the SPL with his first club Motherwell, making substitute appearances in Motherwell's back-to-back defeats to Dundee United and Ross County, and looks all set to feature against runaway leaders Celtic tonight. And Kris Boyd has also returned to his roots, to Kenny Shiels' Kilmarnock - and he too could feature tonight, against Hibernian.
