Looking at the table realistically the lowest we'll probably finish is 11th, we'll have to lose both games and Leeds, Derby and Watford win both of there's to overtake us. Brighton are on a poor run and Burnley lack consistency, looks like it could be us, Leicester and Boro going for the trio of places below the play offs. Hope this is the case anyway!
I did say mathematically. For us to finish 14th like you say we'd have to lose both. As Leeds would have to win both their games that would mean Leicester would have to beat West Ham (as Leeds play Leicester in the last game). It would also need Watford to beat M'boro. I'm not sure who the other games involve but Blackpool and Cardiff are playing teams below us in at least one game each.
