I think Boro may struggle to hold on at the top they have the hardest run in. Watford struggle against the top teams but are excellent against the lower teams. Bournemouth are a bit of an enigma, excellent at times but have a tendency to loose their flow at crucial moments of the season, Friday being a great example.
We also have a tendency to lose points just as we look to be closing on the top, like the Wigan game. We have a concentration issue more than anything, there's no questioning the talent int the squad or even the desire.
We are entirely capable of winning all 6 games remaining to us, so are the other teams at the top though, every dropped point at the top will matter now.
Personally I have felt us and Watford look most likely for the top for a while and I haven't yet changed my mind. If Derby get their whole team fit again I'd fancy them to win the playoffs.
