It's difficult not to admire the aggressive approaches of the Arizona Diamondbacks and Boston Red Sox—two of the biggest spenders of the 2015-16 MLB offseason.

No one knows just yet how it will all shake out, but on paper, the upcoming campaign is looking awfully promising for those two franchises. At the same time, some clubs' offseason overhauls don't look nearly as impressive.

Let's take a trip around the league and explore which teams have orchestrated the best and worst winter rebuilds.

Cincinnati Reds legend Pete Rose will be inducted into the team's Hall of Fame this summer. 

The Reds announced his selection Tuesday. The event is scheduled to take place June 24-26.

With Chris Davis re-signing with the Baltimore Orioles and Justin Upton taking his talents to the Detroit Tigers, we can cross two more teams off the list as potential landing spots for the biggest names believed to be available on the trade market.

That doesn't mean there are no deals to be made, however. From young, up-and-coming stars to established talents who seem to fly under the radar, a handful of impact players could still find themselves on new teams before spring training begins.

At the end of 2016, Hub fans will finally bid adieu to Big Papi. And also, welcome his heir.

In the 1996 sports comedy Space Jam—still easily the best movie ever to feature Porky Pig and Patrick Ewing—a group of aliens led by Danny DeVito steals the powers of various NBA players to construct a hybrid dream team.

That's our purpose here, sort of. Except instead of using basketball greats, we'll be sapping strengths from MLB pitchers. And DeVito isn't involved. 

The Detroit Tigers entered the offseason with a handful of expensive long-term contracts already in hand, and they have since added two more amid a flurry of offseason moves that has overhauled their roster.

As such, it's a little strange we can only look at them as a team with a fighting chance rather than as, you know, a favorite.

Back in November, it seemed the San Diego Padres were taking a risk when they offered $15.8 million to pitcher Ian Kennedy. It seemed like Kennedy was taking just as big a risk when he turned it down.

Seriously, $15.8 million for one year, for a guy who lost 15 games and served up home runs at a higher rate than any other full-time major league starting pitcher? Seriously, he thought he was going to do better than that, especially after the Padres' offer guaranteed he would cost the signing team a draft pick?

We're wading past the middle of January, and Justin Upton still doesn't have a job.

It seems crazy: We're talking about a five-tool 28-year-old here, and baseball is littered with teams that could use a power bat and an outfield upgrade.

Only a fool would argue that the Chicago Cubs and the Boston Red Sox haven't drastically upgraded their respective rosters heading into the 2016 MLB season.

The Cubs and the Red Sox are the kings of the winter, and with that title comes endless hype. It's not easy to measure hype or buzz, but it's also far from impossible.

In order to determine which teams are already being overhyped entering the upcoming campaign, we've considered a slew of factors:

Established stars give an MLB team a base to build around, put fans in the seats and, more times than not, give the team an identity of sorts.

However, young players breaking through and becoming stars that often prove to be the difference in whether or not a team emerges as a contender.

All 30 clubs have at least a handful of promising young players who are either establishing themselves in the majors or trying to make the leap as top prospects.
