It's fair to say we disagree about O'Dea then. I'd move him to left back for the sole reason that Holt makes to many mistakes and until next season a defence of Kerr, Hendry, Meekings (if signed) and O'Dea is better than one with Holt in it.
The goals you mentioned, fault could easily be laid elsewhere. El Bahktoui is the worst offender at the County goal, if he stayed on the post like he's meant too the ball would've hit him and stayed out. Bain could be questioned for not taking the cross in his 6 yard box as well.
The Yenited goal could be the fault of 2 or 3 if we're looking to pick faults.
