Yep, I agree with you but who would you like to bring up from the reserves to get games into ?Not every player is the same or handles things the same.
Hanging your selection policy on McAsey failure to develop is just confirmation bias. Theres many players who thrive in their first year. By thrive, I'm not saying they are instant stars but you see gradual improvement game to game. McAseys failure says everything about McAsey.
You're eventually going to have to go through this development period for players, we.just choose to delay this till it there's simply no other options. This is very bad management.
I reckon Worrell was a good candidate, but I can think of many others ?
I feel Strachan has also deserved a couple of games.
