SWP is a player who is currently playing it smart in regards to his football.
His forte for years has been to charge into players, beat his man and try to get towards the goal. He doesn't do this as much any more so people presume that he is dogshit.
I see a player that is adapting his game as he realises that his pace is starting to go. SWP even more so than Bellamy is the most defensive minded winger we have, I've lost count of the amount of times that he fills in at RB, or drops in to the centre to press an opponent whereas Johnson has that enthusiasm of youth and stays wide (not that there is anything wrong with that).
With Richards bombing forward, SWP is old enough and clever enough to realise that he would be better served dropping in behind than trying to charge forward himself. This also is due to his declining pace. His problem is that when he was younger and was an unknown, he used to beat his man purely on pace, with very little ball control, not unlike Lennon does now. This is probably why he is running into blind alleys man times now, as he is out of ideas on how to beat his man.
Now the positives; there are several things that he still does well. He works hard for the team, he is turning into an intelligent player, he is good in a tackle, he is quite adept at keeping the ball away from opponents, his short passing is pretty good as is his vision for a pass, he can still strike a ball pretty well.
SWP has filled in in the centre mid role a few times this season under Hughes, and he did pretty well there. Despite his size, he does have the physicality for it. I'd definitely give him a go there in this current team, as he has the ability to break well, but not enough to do it on his own, as you would need a winger to do. Can't be any worse than Stevie has played.
Anyway, I highly doubt that he will turn in to a good enough centre mid for us, but will do well at a lower level. This is the way that he needs to go, if he wishes his career to continue. Unfortunately, he seems to be content to get one last pay-day out of us and then retire at 32. Shame really.
