I haven't seen enough of Davies to comment, but he doesn't seem to be worrying the first teamers in the way Savelio or Greenwood have done.
Charnock I really like as a player so happy with him getting a new deal. He'll be vital for us over the next couple of seasons if Roby starts to break down, which presumably he has to at some point.
Fleming is a really strange one for me. We're already more than covered in the outside backs by totally average players in Dawson and Peyroux, so not sure what Fleming offers? He's really slow, really clumsy and I just don't see where he could ever get into a Super League side position wise. Too slow to be a winger and not big enough to be a Carney-esque crash ball winger, not incisive or direct enough to play at centre, and weak defensively. I'd have had him down as being released and getting a gig in League 1 potentially if I had to call based on his first team appearances to date.
His deal is a further reminder of McManus's total comfort with 'okay' as the benchmark.
Having said that I might be wrong, he might have potential and I'm just not seeing it. That can happen with players, I'll admit I didn't rate Greenwood much when he first came through and his development proved me wrong.
