I think smith is quite pacey, nowhere near as fast as mcginn but certainly faster that any of the centre halves.I'd like to see mcniff stay on, hes young and can only get better under murray. How many of the guys pre Murray looked a bit ropey and look at how they have come on to a game post murray. I'm confident mcniff could do the same. It doesn't surprise me, the negativity of some of the sons fans. Used to it now.
