With Sykes - and I said this on one of the other threads last week - I honestly think the problem is that he's not really, truly comfortable playing in that position.
It's fine against teams like Burton, who offered minimal attacking threat and therefore essentially allowed him to play as a winger.
But Ipswich (and to be fair Shrewsbury before them) focused on pressing us up the park down both flanks, and forced Sykes & Williams to play far more in their own halves than either of them would like.
I still think that we are more solid defensively with the 3-at-the-back formation, and so we should on balance persist with it......but one of the downsides is that it likely does blunt Sykes as an attacking threat against some of the better teams, or at least teams that are well coached.
We could play Forde at RWB instead (who I think is more naturally suited to that position, albeit he's not as talented as Sykes) and free up Sykes to play further forwards. Although then you would have to leave out Bodin or Whyte, so I'm not sure about that either.
