I'll go player-by-player and then offer some thoughts...
Smith - 7/10, excellent save at 1-0 and generally solid.
Eardly - 5/10, decent first half, but part of the most brittle defence in living memory.
Zakuani - 5/10, battled OK and did the "head it, kick it" ugly stuff well but as above. Brittle.
Nyatanga - 4/10, inability to concentrate makes him a liability.
Buchanan - 5/10, showed reasonable endeavour but the winner was down his side, again. Left way too exposed by whoever was supposed to be playing left mid, again.
O'Toole - 6/10, most influential midfielder. Popped up with a deserved goal. Lackluster with his passing.
M Taylor - 3/10, game passed him by. Should've been hooked at half time. Lucky not to be given a red card.
Boateng - 5/10, strong and physical. Went missing for long periods. Appeared to be playing right wing for some of the game, bizarrely.
Wylde - 4/10, didn't do anything to suggest he's anything more than a L2 player in L1.
M Smith - 5/10, worked hard & won lots of flick-ons & knock downs. Doesn't look like he knows how to score. Another L2 player in L1.
K Anderson - 4/10, went missing for long spells and fluffed a 1 on 1.
Subs:
Richards - not sure he touched the ball other than for the goal?
McCourt - ran around a lot and made a few tackles.
Beautyman - lived up to his "Invisibleman" nickname.
Justin Edinburgh - 5/10, appeared to ditch the reasonably stable diamond for a flat 4-4-2 first half, resulting in Oldham running through us at will. Seemed lost with how to deal with it, ended up with O'Toole being the only midfielder who ended the half in the same position as they started it. Deserves credit for making proactive changes with time to spare last night. 16 goals conceded in 8 games shows where he's failing.
Overall - Oldham were deserved winners. Yes, we should've scored 2-3 goals in the first half but Oldham always looked threatening and by far the sharper team. In fact I'd go so far as to say Oldham were more willing to do the ugly stuff and throw themselves in front of blocks to get the job done. In the wider picture of the relegation scrap, I'm not confident that we've got enough nous about us to graft out 3-4 wins and see this through.
Good post mate - I think you rated Adam smith a bit too high (his kicking is abysmal and puts us under pressure) but other than that I can't really disagree with your views. I just noticed that boateng was named man of the match - just as well they didn't announce that over the PA system or there would have been a riot!
