Ribs losing flavor

I noticed that when my ribs come off the smoker they taste great, but if I try and hold them a couple hours they seem to lose some flavor. They're still good and the tenderness and juicyness is there, but they just seem to lack something.
Is it just my imagination? anyone else notice a similar issue?

Greasy fingers, lol,
Usually they get eaten right off the smoker, or a short ride on the grill to char them up a little. This time I started earlier and wrapped them in alu and placed in a warm oven till supper, about 2 hours or so till my son got home from work.

They were good,a little over done, but I had one fresh off the rack, just to make sure they were edible...:-D, that to me, was a scootch better. I've had ribs the next day before that were just as good as day one. I don't know...probably overthinking this. Still better then the best restaurant ribs I've had around here.

My thoughts are, if I find myself in this dire predicament again, is to just refrigerate them till the opening act and give them a fast trip on the grill.

It's all good...just curious if anyone else noticed this.
