Rib Rub timing

Rick,
I'm no expert, but I've done a lot of ribs, and I make my own rub, so my opinion would be no, it shouldn't make much difference, with the possible exception the meat may pick up a little more flavor.

Besides..it's good to try different things with bbq.

Drawbacks? I don't see any

The draw back would be they could be very salty flavored depending on the amount of salt in the rub.
I normally only rub ribs a couple of hours before cooking.

I'm like Jim.

I usually rub mine while I'm gettin' the cooker ready ,etc.

They can virtually cure some with these injected slabs and heavy doses of salty rubs, over time.

Some of those Smithfield's from the grocery can get a mite "hammy".
