J.R. Smith is known for his easy-going attitude and he's never shied away from running his mouth. The most recent example of it happened on Instagram, when the shooting guard took a shot at the Golden State Warriors for their playoffs shirts. There is a lot of bad blood between the Warriors and the Cavaliers, and Smith doesn't mind talking trash about Golden State.

These two teams met in the NBA finals in each of the last two years and they will most likely meet again this season. The first time, the Warriors won, but the Cavaliers got their revenge just a year later, as they humiliated the Warriors, and the Warriors blew their 3-1 lead in the series.

J.R. Smith made fun of Warriors' playoff shirts

The Cleveland Cavaliers' motto is "Defend the Land" and they have used it for the entire season. It is what defines them and what they will also use in this year's playoffs. However, the Golden State Warriors decided to change their motto to "Defend the Ground," which isn't really creative and seems like a bad copy of what the Cavaliers use. While the Cavaliers' motto makes sense as they are trying to defend the championship title, the Warriors have nothing to defend and their new motto isn't very bright.

The Golden State Warriors know what they are doing and they most likely did this just to intensify their rivalry with the Cavaliers.

There is simply no reason for them to use the "Defend the Ground" motto and they could have gone with "Strength in Numbers" once again.

The Cavaliers-Warriors rivalry

When you meet the same NBA team in the finals two times in a row, there will be rivalry and heated battles, and that is exactly what is going on with the Cleveland Cavaliers and the Golden State Warriors.

Even though LeBron James doesn't want to admit it, there is indeed a rivalry between these two teams and they are eager to beat each other. Considering that both teams are favorites to win their respective conference, there is a big chance that we see them square off in June this year.

What makes this rivalry even better is the fact that the players of these teams don't like each other very much.

Before J.R. Smith took a shot at the Warriors, Steph Curry did the same to the Cleveland Cavaliers. This is just the beginning since the playoffs started two days ago, which means that we can expect more of it in the next few weeks. Will the Cavaliers defend the land, or will the Warriors avenge their loss and defend the ground?
