The beauty of debate is that we can all argue will dropping help, will continuing to play him help. My initial choice is always to keep playing them to see if they can shake it off. But Foster has continued to play as ade was injured in the last few months. It's not stopped this slide, specifically around feilding kicks and defensive duties.
I think there are a few discussions on these boards and we should not confuse 1 with the other.
There is the discussion about why we lost. I'll say here, Wellens, Lance, Foster are not the reason we lost. The collective team unit defence is the reason we lost.
Outside of that debate, is the debate over who should be playing, we did not have this last year as we played who was not injured.
Ade, Foster, Makinson (well my choice has been consistently Makinson and Foster for 6-8 months, but now I think it's time to try something different to bring Fosters defence back to where it was 12 - 18 months ago, I don't think he is a poor player, but he is playing below his own personal best and at his age he should be improving, not flatlining or going backwards in ability, hence why I put it down to confidence)
Lance ( where to play him, for me the attack is not the issue, the current half back pair have us totting up points for fun, experience; last night shows we need this on the field; I've only seen him for a full game at salford so was not impressed, also Wellens had not had a run out; but given the options this seams to be the best choice for FB to me)
Wellens ( did not want to dismiss from the old he's slow arguement, this was being said before he picked up a ball this season, everyone deserves a shot; I still think it's daft to suggest retirement, however given Lance would be a better FB, we then have to say well can Wellens be anywhere else? He is a Saints lad through and through and would probably do anything for the team, he is also a proud pro and wants to play, dismissing him as a back on the bench in favour of say ashe, who would sit there for 75 mins seams just as daft. He can come on and do stints giving other players breaks, whether that be at loose, acting half back, cover for centre spots if injured, moving to FB if FB or half back is injured. Saying he is limited to FB or nothing is a discredit to the man, he can play elsewhere and has done and would do again if asked to)
