If you didn't know any better, you might not have known which team was rebuilding and which team was already built Friday afternoon at Camelback Ranch.
Both the visiting Cubs and the White Sox used reasonable facsimiles of their opening-day lineups in their St. Patrick's Day showdown, and the Sox were older than the Cubs.
Other than Ben Zobrist, 35, and Jon Jay, 32, none of the Cubs was older than 28. The Sox countered with six players over 30, including starting pitcher Derek Holland.
Like snowflakes, no two rebuilds are exactly alike, and the Sox appear intent on starting theirs with most of the same position players who ended the Robin Ventura era in 2016.
