For two reasons:
1) I hate tuz's hivemind hate session, when one player is singled out and bashed to oblivion. It happened to Sami, now it happens to Blaise, while players who were equally shit or even worse are walking scott-freem because they have flair, fancy or whatever.
2) I do believe he wasn't the worst player on the field. The way I watch and understand football Blaise was not the main culprit, he just looks terribly, but he didn't play terribly. Well, he did, but not the worst, far from it.
