It's been a while but it's another good video.

I don't know. I agree that attacking earlier through the mud may have been an issue but I think that concentrating forces for an attack on one axis would have been the better course of action.
The Russians still had limited forces so I don't know how much they would be able to concentrate lest they risk another Kharkiv. 
And additionally, Ukraine has the advantage of interior lines of communication, so they can redeploy faster than Russia can.

I think the issue would have been that they would risk losing ground around Bahkmut if they didn't have those forces there but that would have been a worthwhile trade-off.
