Smoking a chuck mock tender roast-- wasting my time?

Don't know that I'd smoke it, but it would be fine in a crockpot.

I do those pretty regular on the smoker. I dry rub it and let it sit in the fridge overnight. It smokes for a cpl hours over oak. I put it in a small foil pan with some beef broth and dry rub combined. Cover it up with foil and put it back in for a cpl hours until tender. Like Madam said, slice it up thin for sandwiches. It's very good.
