It would be cowardly to wait until Hull avoid defeat against Man City before I say it, so I'll say it now:
Hull aren't that bad and Swansea are the only truly terrible team in the league.
Every team bar Swansea has found a formula. Sunderland and Hull look a lot tighter in recent games and along with Middlesbrough and Burnley, are teams that won't score too many but won't concede that many either. I do think the relegation spots will be completed by Swansea + 2 of the others I mentioned, but not easy to pick which two.
