This thread tends to cycle the same topics often but Opie is fine. He was never the funniest but he was never supposed to be - he just kept the machine running.
When he was missing - it was very sorely felt and some of the most unlistenable radio ever produced was when Anthony was at the helm (See also - Compound Media). Sure, every bit wasn't a hit - some of the were cut short, some went on too long, some were given too big a slot on the show (like Bobo, christ) - but he generally knew how to keep it all moving and what pieces fit together for the show.
Opie is the only cast member that gets better with hindsight - because of how much the masks slipped off of Anthony and Jim; revealing how much they are just angry, retarded, and spiteful children who needed to be tard wrangled behind the scenes constantly, with Opie doing the wrangling. The worst Opie did was step on some bits, push his brother's restaurant way too hard, and put too many retards on the show. Him shitting on Danny Ross is much more favorable now that Danny turned out to be such a miserable cunt as well.
