The locker room altercation occurred with linebacker IK Enemkpali after Smith didn't repay Enemkpali $600 for a plane ticket to Enemkpali's football camp (which Smith missed for personal reasons).
Certainly Enemkpali crossed the line with the punch, but the story behind the debt gives more background as to why the altercation occurred. Enemkpali was cut and Jets head coach Todd Bowles said afterward "you don't walk up to another man and punch him in the face."
In the aftermath, however, including the money he owed Enemkpali, sources are painting a picture that suggests Smith provoked the fight.
On Wednesday, ESPN analyst and former NFL safety Ryan Clark said that Smith wasn't apologetic about owing money, and put his finger in Enemkpali's face and said "you're not going to do anything about it":
"It became about the fact that Geno wasn't necessarily apologetic, and being in a way remorseful about the money, when saying he was going to pay IK back. You know, he didn't, and he was rather smug about it. So these guys got into it earlier in camp about this money. My report says Geno put his finger in [Enemkpali's] face and told the guy, 'Well, you're not going to do anything about it.'"
Clark also said it wasn't the first time a situation arose between the two players, but the first incident ended with both players walking away. Clark reiterated on Twitter that while Smith didn't deserve to be punched, it also shouldn't be considered a "sucker-punch":
I guess just knowing the story I felt people should know he wasn't sucker punched like an innocent by stander watching a fight. He was in 1

Like I said though. Under no circumstances did Geno deserved to be punched. Their disagreement doesn't excuse violence. Sad deal

Smith "was up in (Enemkpali's) face and pointed/touched his face," according to a source.
"Geno deserved it," another source said.

It's unclear how matters escalated, but Smith's finger-pointing in his teammate's face was grounds for a punch, according to some.
"That'll get a man hit every time, especially one that hasn't earned respect," a source said.
