Theo Epstein answered questions from the Chicago media for more than an hour on Friday afternoon at Wrigley Field, but the most interesting part might have been what the Cubs president didn't say, something along the lines of: These are our guys. Or at least Epstein didn't give the same full-throated endorsement of The Core that he delivered after engineering the Jose Quintana trade with the White Sox this summer, getting an All-Star pitcher without giving up anyone from the big-league roster. Whether it's the way the Los Angeles Dodgers dominated the Cubs throughout the National League Championship Series that ended Thursday night, the inconsistencies and frustrations during a 43-45 first half of this season or the reality of losing 40 percent of the rotation, you walked out of that stadium club press conference thinking big changes could be coming.
