Man of Honour
I think Discovery do a good job with sport generally, often covering the "2nd tier" stuff that just wouldn't get coverage elsewhere; often the same stuff the BBC covers (like Snooker) or even ITV (cycling).
They're certainly moving in the right direction with their online/mobile coverage and the apps work really well generally.
