Will there ever be a Good Civil War TL?

He didn't get the neccesary number of horseshoes for another 3 days! Do your research

Even if you ARE a professor this will happen! :(
You are right. Suppose you start a UVTL where the POV is Grant's occupation of Belmont. You put in your opening post that Grant gets his command a little earlier because somebody "sees something in him" and Grant moves into Belmont a week earlier. That's it so far. BOOM! From the getgo you can expect haughty replies that no one would have trusted Grant with such a command any sooner and it was a miracle he got it at all! And angry replies that according to the supply manifests of the time Grant's command would not yet have been issued uniforms, weapons, rations, ammunitions, pay, horses, etc., and so forth, and CLEARLY showing the TL to therefore be TOTALLY ASB. Except that anybody who has access to those Union Army supply manifests would have to be walking though the US Archives, or the libraries of VMI or West Point. Thereby having the "ammunition" to shoot down any such UVTL they wish, even if only over minutiae. VERY discouraging.
