Since nobody is really defending Ritchie Allen, I would just like to throw something out there. Ritchie could have bowled a 200 from where he was at by catching a string or a couple of doubles, but he was forced to move. Angelo started with the front five, and Ritchie had poor carry. That means he has to try and move to make his ball carry so that he could win the match. This is why he got lost and shot 160. Anyone who has ever moved to try and find carry knows how easy it is to lose the pocket, especially on a difficult pattern.
As for everyone else, you have to look at what they are trying to do. When you are bowling for a title like that, you either need to out execute your opponents from the same area, or find a look they don't have. Mika trying for the different look option since he has great control of loft and that is probably where he played much of the week, but he had to adjust his look and by then it was too late with Angelo bowling so well. Chris Barnes could have gone in, but I don't think he could have gotten the same look as Angelo due to how Brad throws the ball, and he obviously didn't like his look from inside. Plus, after seeing Mika figure out an outside shot, he probably felt there would be something out there for him to find, and this would also give him a different look against Robert Smith. Unfortunately for him, it didn't pan out. Smith likely decided after seeing two straight players struggle (except the later part of Mika's game) and with his rev rate and physical abilities, he should get in, but he should find a different part of the inside. He did so, and guessed right.
