Extremely concerning that the ECB are allowing Cook and Flowers to continue. They, and all the coaches should go, a complete overhaul. This might sound an overreaction but look at it:
Batting - Problems have been there for years now, England are brittle against just about every type of bowling. There's no evidence of any improvement above any of them, its pretty damning that the best batsmen for England has been Stokes who hardly a renowned batsmen himself, and who's been relatively "untouched" by England coaching. Likewise Root and Compton look increasingly poor as time with England goes on.
Bowling - Probably the most damning to come out the whole thing was the complete lack of balls being bowled at the stumps, 5% I think it was. Bare in mind they had Watson, a walking LBW, and a tail constantly scoring runs - Lyon wasn't bowled out once, you'd have to say this would be very different had England not taken LBW and bowled out the equation pretty much constantly. Who decided this tactic? It makes no sense at all, 5 games we persisted with it. Whoever decided such bowling tactics is either lazy or clueless, or probably both, and really needs to go. If it was the players ignoring plans then they should be dropped. England might not have bowlers quite as fast as Australia but they can still go pretty fast, fast enough that the part time batsmen will miss one eventually and got bowled rather than letting them slog you till they eventually get caught. The less said about whatever they've done to Finn the better. Lesson's about overcoaching should have been learned from Anderson.
Cook - Doesn't even deserve to be in the team. 10 games, very poor, his average is dropping remarkably and he really hasn't looked even test level, yet alone one of the great opening batsmen as he supposedly should be. If this continues he's not meriting his position regardless of captaincy, but the concern is the sheer amount of basic mistakes he's making. Several times now he's been bowled or got out LBW by deciding to leave the ball, its inexcusably poor for that to keep reoccuring. As a captain you get the feeling everything's already planned pre-match and it its not working he really has little idea where to go. Compare how Clarke uses the bowlers for example to Cook, Cook you get the feeling has pretty much a pre-match rota of how the bowling will go, Clarke chops and changes the bowling constantly based on who's looking dangerous, not troubling the batsmen? He'll take you off after 2 overs and give someone else a chance. Complete opposite to Cook who basically summed it all up by continually bowling Rankin in Australia's last innings towards the end despite the obvious wicket threat of Broad and Stokes.
Flowers - Did great things initially but the team has gone backwards in every department to be worse than it was when he took over. Shouldn't be forgotten how he transformed England into one of the best teams in the world, but there's very little to suggest he knows how to improve things now. Particularly odd of late have been the team selections, Joe Root has been ruined, a capable middle order batsmen, terrible at the top of the order, yet England are insistant on having him there. Constantly changing through openers - Compton who after one decent series, one good series, and one bad series has ended up dropped entirely, Carberry it remains to be seen what will happen. Then just flat out bizarre decisions like picking Woakes and Kerrigan in the 5th test last summer, but then neither of them seemingly been considered good enough to even make the touring squad for the following series. Kerrigan in particular it seems is behind at least Panesar, Borthwick, and Tredwell so there really appears to be little logic in it.
Not that the actual players should in anyway avoid a large chunk of the criticism mind you. Stokes and Broad aside they could all be dropped for the next match, and not a single one could have any complaints. Cook, Pieterson, and Bell will keep their places on reputation rather than merit but the rest is anyones guess. It won't happen but I'd like to see Anderson dropped for the Sri Lanka series, give someone else a chance. Either he's in terminal decline now, in which case he needs dropping regardless, or he desperately needs some time out the firing line, in which case a start to the summer in the county game to get some confidence and return for the India series should do him so good. As it is he's really not been much a wicket threat. Of course a big problem is there's no real obvious candidates to come into the team - openers if Carberry gets dropped? Who? Spinner to replace Swann? Wicket keeper? Prior has been awful for many games, Bairstow is worse, and Buttler despite many peoples claims, is not a good enough batsmen for test cricket.
Long post. A lot to be annoyed about.
