Why is it when I use drummer with existing guitar tracks, it sounds awful/sloppy?

Hi everybody,

I've watched a bunch of tutorial videos and I'm still doing a deep dive on this.

But, if I've recorded guitar tracks and I'm in time with the metronome, why would the Logic Drummer sound sloppy? Any advice on what I can do? Is it the strumming pattern?

Any explainers or videos that you can share would be helpful.
