Agreed that Dechaine will not have Earl's career -- but who said he would? The comparison is of them today. Earl is rightly celebrated as one of the all-time greats but his resume is a little thin in the last year or two.
Anyone can beat Shane? At the Derby, Shane went 4-0 in ten ball and 11-1 in nine ball. The only guy who managed to beat him was Mike, who did so in their only meeting. Sorry, but the track record does not bear you out. The truth is that, in a short race, pretty much no American ever beats Shane --- except Mike. Nobody beat Shane at the US Open 9-ball in the short races there either. Sounds to me that you're not giving Shane his due. Two biggest losses by Shane in 2013 were to Biado at the World 9-ball Championships and Appleton at the World Pool Masters. Only the truly elite knock of this superstar, even in a short race format.
Also, I agree that Mike D would be a big longshot to beat Shane in a long race, but the premise of the thread is only that he's the best of the rest among American pros, that his results make it pretty obvious, and that people tend not to give him credit for his accomplishments because they don't like him, and your post evidences this.
Pool is about what you have achieved, not about reputation, and of late, the guys you respect the most haven't achieved much. That doesn't make you wrong to respect and appreciate them, just as I do, but it does show that you have no respect for a player that has outperformed them over and over, and that's really the main point I made in this thread's original post -- that many feel as you do.
I guess you must feel that Mike out-achieves them all with smoke and mirrors.
