Sam can be very good for us, but his performances have faded largely along with the rest of the team. I'm not sure if the team fading influenced him not playing well or the other way around but he can be a good player. So the notion of 'get rid' as mentioned earlier is quite frankly ridiculous. You 'get rid' when better players have come in, not before that if you don't like their current form.
I would like to see Weston given a chance though, he's not seemed bad in the glimpses we've seen of him in the past several games. A team with Forrester, Weston and Saunders could be pretty good imo, if they could all be fitted in.
