Couple of years ago when our band was recording in the studio and I did my bass parts, the engineer noticed that my bass playing seemed to be a tiny bit behind the drums, but when listened in full mix it sounded just fine. So I think sometimes "bad timing" or "sloppy playing" could just be that the bass player is playing in the groove and when isolated it might not sound right.
Another thing worth mentioning is that you dont actually need so much low end as you might think, often it can just muddy up the tone. On the other hand, distorted bass track can sound bad alone but usually it sounds good and present in the mix.
