In sports history, most great players and teams show their best performance during rivalries. It\’s not only good for the players but also the fans. If not for rivalries, some sports would not have its best moment and individual performances. We would never be able to compare the difference of the Manning bothers\’ games. Defeating a rival team makes victory feel even better compared beating just any other team.

Here are two of the recently formed rivalries that you should watch out for.

The Indianapolis Colts-New England Patriots Rivalry

In the years that the Colts and patriots were division rivals, their rivalry didn\’t spark much interest in the NFL until lately. It was the quarterback battles in the patriot and Colts roster that led to this fabled rivalry. The patriots drew first blood when they claimed victory in the 2003 AFC championship game and 2004 AFC divisional game.

The colts returned by winning in the 2006 AFC Championship in their campaign to take the Super Bowl in the same year. After that, the next two matchups were split and there was just a small difference in the final score. The last game was claimed by the Patriots which the Colts almost stole again.

The Miami Heat-Boston Celtics Rivalry

One of the most recent rivalries in the NBA is the one between the Heat and the Celtics. The rivalry began when the Heat acquired their much younger big three a couple of years ago. At this point, the Celtics already had their own aging big three in Kevin Garnet, Paul Pierce, and Ray Allen and an emerging point guard in Rajon Rondo.

In the two seasons that followed, the two rivals met in the playoffs where Miami won in both occasions. In both times Miami went through to the NBA finals and won the crown on their second attempt. Because Ray Allen; one of the Celtics\’ big three, transferred to the Heat in the preseason, the rivalry became even more interesting. Fans are surely looking forward for these two teams to meet again in the playoffs.
