Indianapolis Colts were once a unit completely at one with each other. Tragedy brought them together when Chuck Pagano was diagnosed with acute promyelocytic leukemia during the 2012 NFL season. But it seems that those united days are gone.
Now we all know that NFL teams have a vast amount of players on their rosters. This means that the normal amount of issues that sports teams suffer are magnified because of the sheer number of players in the squad.
So when we see problems between teammates more in the NFL than other team sports, it's not rocket science to work out why.
However, sometimes opportunities to bond with teammates go wrong, and one of the players is to feel the brunt of a bad decision this summer was former Colt Chris Rainey. He was released from Indianapolis several weeks ago for a breach of player conduct, and it seems like he's still not taken the news very well.
Taking to Twitter during the Colts opening pre-season game against the New York Jets, Rainey sarcastically praised a former teammate, before he suggested that his former teammate Daniel 'Boom' Herron should have stepped up and received the same punishment as him.
"Nice TD Boom even though you was in the hallway with me that night when we was horsing around with the fire extinguisher. Man up like I did," Rainey tweeted before adding.
"Yeah I'm pissed watching the Colts game when I should be out there too. Even though I didn't break no f***ing team rules, not even."
Other forms of crazy teammate tension have reared their head so far during the pre-season. There is the competition for places that also brings out a rivalry that can go overboard. Chicago Bears have been one team to already see what happens when teammates fall out on the practice field.
The Bears OTAs started off in an explosive fashion with a four-man brawl back in June. Intense drills caused tempers to flare, and defensive ends Lamarr Houston and Jared Allen fought with right tackle Jordan Mills and tight-end Martellus Bennett, with Bennett slamming his helmet down in frustration.
But unlike the Colts escapades, nobody was released from the Bears as they continue to tread the line between good competition and destabilising competition.
