Think all commentators and pundits outstay their welcome at some point (apart from true greats like Richie Benaud). You can tell when someone produces a Bingo sheet of their sayings. Stevo was a classic case.
People used to moan like mad about Eddie Waring and Ray French being out of touch and a bit "northern music hall" but the players who those blokes commentated on held them in great respect. We have moved on a long way from the days of the "up and under" and "the 6ft 4, sixteen stone, former Blackbrook AMATEUR player".
It's a difficult job as you need to inform, educate and entertain. Catering for a terrestrial free to air TV audience with massively varying levels of understanding is a challenge too. Too much jargon and technical talk will turn off the average sports fan and too many cliches will annoy Seth and anyone else that wants a bit of insight. It's a balancing act.
