One thing that struck me when watching Tarkowski at Wigan was that he's not making any forward runs -- even Tony Craig was more adventurous. However, at Oldham that was a key feature of his game, and when I saw him play for them he reminded me of Des Walker in that respect. Presumably the fear is that he will give the ball away and expose the defence, but it's not that difficult to cover for a central defender who makes forward runs. I lived in Nottingham and used to watch Forest a lot. Each home game Walker made several forward runs and they regularly opened up the opposition. If he lost the ball, others had covered and they simply worked hard to defend -- it didn't seem a big problem. I think we're missing out on a useful aspect of his talent. Either way, though Harlee is a good player I think Tarks is a better one and would prefer to see him in the side.
