The Miami Marlins, who were well known for blowing up rosters in the past, have struck again in one of the biggest trades in the modern history of MLB. They sent former and current All-Stars to a Toronto Blue Jays team that is looking to contend in the AL East with the likes of the New York Yankees, Baltimore Orioles and Tampa Bay Rays. While this might not make Toronto favorites in that ultra competitive division, it sure does alter the landscape of both eastern division leagues. 

Here is a breakdown of the deal. 

Yes, that was a 12-player trade involving hundreds of millions of dollars. No, the Miami Marlins did not improve their roster by sending some of its best players east to Toronto. Instead, Miami made the unpopular decision to scrap everything and start anew for what seems like the 10th time in the last two decades. Mere weeks after firing Ozzie Guillen, Miami seems to be right back in rebuilding mode. Not what most of us expected for a franchise that had a $100 million payroll and new stadium just a few months back. 

They did, however, get a whole host of youngsters upon which to build. 

Baseball America had Jake Marisnick as the Blue Jays No. 2 overall prospect entering the 2012 season. He is a five-tool talent that promises to be a dynamic player moving forward. The youngster hit .320 with 14 homers and 77 RBIs for Toronto's Single-A affiliate Lansing back in 2011. He did struggle in AA ball this past season, hitting .233 in 55 games for New Hampshire. Expect Marisnick to get more seasoning in the minors before punching his ticket to the majors. 

Henderson Alvarez was one of the youngest regular starting pitchers in MLB last season. He won nine games and boasted an ERA under five at the ripe young age of 22. Expect him to open the season in Miami's rotation. 

Adeiny Hechavarria, who defected from Cuba back in 2010, is currently playing under a major league contract that pays him $10 million over the next few seasons. He was mighty impressive in terms of fielding and handling pitching as a youngster for Toronto this past season, though his numbers don't seem to indicate that. Depending on what happens with Yunel Escobar, who Miami also acquired in this deal, the young Cuban should be starting at short in April. 

Speaking of Escobar, he struggled tremendously at the plate for Toronto in 2012. He hit just .253 with nine homers in 558 at-bats. Pure conjecture here, but I strongly believe that Miami will attempt to flip him for more prospects. A team like the Oakland Athletics could show some interest and provide the Marlins with a couple mid-tier prospects in return. 

Meanwhile, Toronto fortifies a rotation that was as inconsistent as any in the majors last season. Brandon Morrow was its only regular starter to finish with a winning record and ERA under 4.50. Buehrle and Johnson provide top of the rotation stuff and should help that unit improve drastically from the top down. 

This is what their rotation currently looks like: 

Much better than what we saw last season. Toronto now has the arms to go up against some tough lineups in the AL East. While acquiring these two solid starters, the big win here for Toronto was being able to bring in Jose Reyes, a four time All-Star and career .291 hitter. He will be a dynamic performer atop the Blue Jays lineup. 

Look for Bonifacio to split time in left as well. He provides a tremendous amount of speed and is just one year removed from a solid .296/.360 split. He could eventually be an upgrade over Rajai Davis. 

It is important to note that Toronto's offense was a strong point last season. It hit nearly 200 homers and scored about five runs a game. Get better pitching and this team could surprise a great deal of people in 2013. 

This lineup doesn't look too bad. Does it? 

In reality, the AL East race could now include all five teams depending on how much the Boston Red Sox improve their roster. As it is, Toronto definitely closed the gap between itself and New York, Baltimore and Tampa. That is all they could ask for.
