A remodeling job can take weeks, even months, to complete. Red Sox General Manager Ben Cherington decided he didn’t want to wait. In two days, he completely overhauled the Sox starting rotation for 2015. There may be more moves to come, but there’s no doubt we’ll see a drastically different group of pitchers when the team hits Fort Myers, Florida, in just two months.

The action started at baseball’s winter meetings in San Diego when Jon Lester signed a free-agent contract with the Chicago Cubs. It was a serious blow to the Sox, who had hoped the left-hander would return to Boston to resume his career.

Still, Cherington refused to pay beyond what he thought was fair market value for Lester. Theo Epstein, desperate to end a 107-year championship drought in Chicago, was willing to offer Lester more. So he landed the ace. That lifted a logjam that had stifled the deal-making in San Diego.

And Cherington got to work.

He landed three starting pitchers in their 20s, all with a track record of major league success. Yet none can be considered a true ace at this stage of his career, leaving Red Sox fans to wonder if there is yet another deal to be made.

Rick Porcello will celebrate his 26th birthday later this month, and is coming off the best season of his career. He went 15-13 with a 3.43 ERA on a Tigers pitching staff and was overshadowed by Justin Verlander, Max Scherzer and, eventually, David Price.

Justin Masterson, originally drafted by the Red Sox, returns to Fenway Park coming off an injury-plagued season. An All-Star in 2013 when he won 14 games with a 3.43 ERA, Masterson won just seven games in 2014 while watching his ERA balloon to 5.88. It was a classic “buy low” free-agent opportunity, and the Sox pounced. They’re hoping a fully healthy offseason will allow Masterson to once again become one of the most promising young right-handed pitchers in the game.

Wade Miley, the new left-hander, was runner-up for the 2012 NL Rookie of the Year with Arizona. He’s been a workhorse, throwing 190 or more innings in each of the last three years. And he’s only 28 years old. But he struggled this past season, winning just eight games with a 4.34 ERA. The Sox believe that Miley, a ground-ball pitcher, was hurt by a notoriously bad Diamondbacks defense in 2014.

In fact, the Sox are banking that a strong infield defense will help all three new pitchers. Porcello, Masterson and Miley are all at their best when they are inducing ground balls. The same is true for Clay Buchholz and Joe Kelly, the two pitchers who have survived Boston’s rotation overhaul.

Well, they’ve survived it so far. There were rumors at the end of the winter meetings that the Sox could still be kicking the tires on a Cole Hamels trade with the Phillies. That would make Buchholz or Kelly expendable.

Landing Hamels – or Scherzer or James Shields via free agency – would give the Sox an arm that could cement this rotation as the best in the division. While Cherington gave up a lot at the meetings (Yoenis Cespedes, Rubby De La Rosa and Allen Webster were the biggest names to go), he held onto most of his key young prospects.

So the dealing might not be over. It’s mid-December, not mid-April. Manager John Farrell doesn’t have to figure out his rotation for another few months.

Which gives Cherington time to continue the remodeling project that he ramped up over the past week.
