The greatest test of fundamentals each year is the Bigfoot Challenge (formerly called the Fatboy), a 10-ball event played on 10 foot tables during the Derby City Classic. Every year, the field includes Americans, Europeans and Asians. Here are the winners:
2009 Lee Van Cortezza
2010 Efren Reyes
2011 Rodney Morris
2012 Bustamante
2013 Orcullo
2014 Van Boening
2015 Van Boening
By continent, Asian has four wins, America three and Europe none. The top Americans shoot ridiculously straight playing in the toughest event, and the format and conditions tend to reduce the frequency and, consequently, the importance of defense and kicking, which helps American chances.
In regular tournament play and, of late, every year at the Mosconi, I think it's the safety play that's Europe's biggest advantage over America, with kicking second biggest. I think Americans run the table nearly as well as the best Europeans and Americans also break a little better, but they are far inferior to Europeans in tactical battles for control of the table on the nine footers.
Of course, in the last Mosconi Cup, one American player shone in the tactical play and that was Justin Hall, and his inclusion on the next Team USA is even more obvious than the inclusion of Van Boening.
