Dave:
Well, that's pretty evasive, isn't it? You don't want this to be a CTE thread, but you still want to "direct attention to it." Hmm... sounds like you're throwing wads of steel wool into the energized fusebox again, and while the shower of sparks ensues, quickly running upstairs so noone sees that you were the one that did it.
Dave, you're so locked into looking for signs -- gosh, any sign(!) -- that a player "might" be using CTE, that you're neglecting that Efren is stretching over the table and re-situating himself. It's obvious he had to make adjustments while situating himself, and after realizing he couldn't reach the shot, he lays the cue down on the table, sights down it, realizes he's a bit off, makes a minor adjustment (that thing you're mistaking for a "pivot"), lifts the shaft of the cue with his bridge hand (so he doesn't "dig" under the cue ball as would happen if he left it flat on the table), and then bumps the cue with the heel of his hand to deliver it. That doesn't look like "signs of CTE" to me, especially when you watch Efren, he doesn't pivot at all in normal shots. And I happen to know something about Efren -- he's a contact point / <gasp!> ghost-baller. I asked him (I've an autographed cue ball from Effie).
BTW, I know you personally know this, but I'm not one of those that negates CTE or claims it doesn't exist (to speak to Koop's post). We all know of many players that use it (e.g. Bustamante, Robb Saez, etc.). But "just because Efren's Filipino, gosh, he 'must' be a CTE user, right?" Wrong.
