Have you not watched any of the PBA telecasts in recent years Pete??? They have Randy Peterson as their informer/insider, as you put it, and often another person, who is either a Journo or TV presenter from another area in TV. Randy has also done many short clips, which they've showed in many of the PBA telecasts in recent years, that aim to educate the casual viewer on the nuances of the game. He's compared house shots to all of the different animal patterns, so the casual viewer, even the casual league bowler, can clearly see the difference in ball reaction from a THS to an animal pattern. They've also used the blue oil, which I think helps explain to casual viewers why the pro's are bowling in those particular areas of the lane.They also have plenty of drama, with interviews from the pro's & of course, the much publicised Rash/Belmo incidents & PDW losing his sh!t after winning his 5th US Open.
Every xgames video I've attempted to watch, I've never ended up watching the whole thing. I found it hard to keep track of who was in front, or how far into the match we were, and quite frankly, I found it boring to watch. I'm still going to watch these latest PBA telecasts, when they become available on Xtra frame, so I will reserve judgement on the WTBA system that they employed in the WTBA finals telecast, until I see it. But again, I don't think changing the scoring system is going to fix bowling. Just my opinion.
