Whilst I agree that some people are maybe overreacting to the state of things (which is nothing new), I don't think all of the complaints about the squad situation can be dismissed on the basis that the squad will look different by the end of the window.
As we know, players take time to bed in, they've all missed the entire training camp now, and their physical condition will probably be the next problem for us if they're coming in late. The last thing we need is another injury situation like we had two seasons ago and that was blamed on a disjointed pre-season. Hopefully TW will be maintaining or building on the work LR did in that respect, but it can't help him if he's relying on signings coming in and being immediate starters week in week out at Championship level, like Shota had to do two years ago. That year the injuries snowballed because the set of injuries we started the season with meant that everyone left had to play way more minutes than they should've been doing, and then many of those started getting injured too.
If we find ourselves with an injury crisis in the autumn/winter time, we can't say it's just bad luck and nothing could've been done...
