Weird thing radio broadcasting. I've met Drury a few times and he's a really nice genuine bloke but I can see why his commentary rubs people up the wrong way, it comes across a bit smug and sarky and self-important.
Not sure what it is, might just be the sound of his voice over two hours or maybe he's a bit opinionated and trying to be funny for the guy who's supposed to be the describer, and the other guy is meant to do the colourful stuff.
The new guy's way better. Sure Tees will transition him in if they keep getting good feedback.
