Think London have been talked up a bit too much. Yes their fulltime and have a useful starting 13. Their strength in depth drops off rapidly after that though. Wouldn't be surprised if they ended up mid table at end of year.
They got out of jail against Doncaster last week. I think the problem is that unlike ourselves London have pretty much started from scratch with their new team and will take longer to form a solid core around which to build on. I wouldn't put too much in a few early season wobbles.
Sheffield are no mugs, and will be a test for any side, especially once the pitches firm up and the weather gets better. That being said, today's result - and certainly the final score - is a big shock. Ruined my accumulator as well, the swines.
