Does black drum taste any good?

I don't go fishing in south louisiana that much, but the few times I've been, we've caught a good bit of black drum and just tossed them back since the guy that took us said they were no good. However, my older brother said they were good to eat. So now I'm confused.

We're going again this next weekend and was wondering if I should keep the drum if we get any.

TIA
