KOvac is a complete and utter moron, Green had to release the ball or concede a freekick deep in his own box for holding it too long. If he punts it out and Kovac is kneeling in the box, Brum can just leave 5 players in the box, and if someone punts it straight back in the box West Ham are screwed, do up your laces up but get the **** up the pitch first.
West Ham were great in the first half, and Birmingham were great in the second half for the same reason, commiting men forward. West Ham kept Brum pegged back by attacking hard in the first half, but they came out wanting to defend the lead, which allowed Brum to push forwards and do exactly the same thing in the second half.
After Cole/Hines came on there was a few minutes West Ham actually got forward again and instantly Brum were sitting much deeper, fair result overall, stupid red card, awful BBC directing in general as they managed to miss almost the whole incident, took ages to show a replay and you've got to assume that Larsson did something to upset Obina and they didn't manage to show the few seconds before the daft kick.
West Ham have been capable of that first half performance all year, they've done it in LOADS of games, the played great against the good early season Chelsea, but they tend to always drop deep and cause themselves ridiculous problems in every single game, throwing away so many points.
