Ranking MLB's best lineups after Heyward deal

The early offseason winners reside on the North Side of Chicago, as the Cubs wrapped up the winter meetings with a bang.

The signings of outfielder Jason Heyward and utility man Ben Zobrist came within a 72-hour window that saw the Cubs swoop in and land two of the most prized free-agent bats on the market.

After bowing out meekly in the National League Championship Series, the Cubs became a more complete team with their offseason additions, and are now the early-season favorites heading into 2016.

Here's how they stack up among the best lineups in the majors:

Chicago Cubs

Theo Epstein has created a monster. Since taking over at the conclusion of the 2011 season - a 91-loss campaign - the Cubs president has masterfully constructed baseball's most complete offense. Epstein complimented a young core that exploded onto the scene in 2015 by spending a combined $240 million on Heyward and Zobrist to address the roster's two major holes. No team in the majors boasts an offense in which one-through-eight are capable of hitting double-digit home runs, and the scariest part is this group has an average age of just 25.

Toronto Blue Jays

It's hard to ignore an offense that scored 127 more runs more than the second-highest team last season. The Toronto Blue Jays will return their entire offensive core from a year ago, and will only be bolstered by a full season's worth of production out of Troy Tulowitzki, Ben Revere, and once he returns from injury, Devon Travis. There is no easy out in the Blue Jays' lineup: If the opposition survives the 120-homer gauntlet of Josh Donaldson, Jose Bautista, and Edwin Encarnacion, they have Tulowitzki waiting.

Houston Astros

Though the Houston Astros struck out more than 28 other teams, they also hit the second-most home runs in the majors, and boast eight hitters that have 20-homer potential. Though the back end of the lineup drops off, Houston owns arguably the most talented one through four in the majors. Jose Altuve, George Springer, Carlos Correa, and Carlos Gomez are not only threats to go deep, but they also blend in an element of speed on the bases. The foursome combined for 65 home runs, 110 doubles, and 85 stolen bases in 2015, despite Springer and Correa combining for just 201 games.

Boston Red Sox

The Boston Red Sox return the same lineup that scored the fourth-most runs in the majors last season, despite ranking just 15th in home runs. David Ortiz anchors a youthful core as the only legitimate 30-plus homer bat, though a healthy Hanley Ramirez could give the team a second. The Red Sox lineup is constructed as a team that gets on base plenty, while rarely striking out. But some potential trouble spots remain in the bottom four. They'll be banking on youngsters Jackie Bradley Jr., Rusney Castillo, and Blake Swihart to all take the next steps in their development at the same time, while also hoping that free-agent bust Pablo Sandoval wakes up.

New York Yankees

Health is the biggest threat to the New York Yankees' high-powered offense. With an average age of 32, the Yankees' order is laced with veteran hitters who own impressive resumes; manager Joe Girardi will need to blend his balance of young, up-and-coming hitters with his aging sluggers in order to avoid another disappointing falloff like they experienced last September. Alex Rodriguez, Mark Teixeira, and Brian McCann proved there's plenty of life left in their bats last year, while Jacoby Ellsbury should bounce back from one of the worst seasons of his career. The addition of Starlin Castro finally solidifies the second base position.
