#2. There's a role for the Skrap Pack
Despite his reputation, Nate Diaz is not confrontational or hostile towards every fighter he encounters. Diaz exhibits unconditional loyalty to the members of the Skrap Pack, a group of Cesar Gracie Jiu-Jitsu pupils.
Consisting of Diaz's primary training partners Jake Shields, Gilbert Melendez, David Terrell, Daniel Roberts, and, of course, Nick Diaz, the Skrap Pack is his longtime entourage.

Given Diaz's past of using his rapport with the UFC to try and earn his other training partners UFC contracts, it stands to reason that he would likely bring the Skrap Pack with him to the WWE.
The MMA standouts will find a built-in storyline role should Diaz introduce them to the world of pro-wrestling. As a faction, the Skrap Pack can easily be booked into the role of tweeners who come to the aid of other more established tweeners like Kevin Owens.
Addiitonally, due to Nate Diaz's friendship with Ronda Rousey, the WWE can book them together in an Invasion-inspired storyline revolving around MMA fighters taking the pro-wrestling world by storm.
#1. Diaz's otherworldly toughness
From the beginning of his MMA career to its end, Nate Diaz has always been known for his unbelievable toughness. The durability and iron will possessed by the Stockton legend were so great that many fans erroneously believed Diaz had never finished in an MMA bout, discounting his lone submission loss to Hermes França as well as his TKO loss to Josh Thomson.
He was outrageously difficult to knock out as Conor McGregor and Leon Edwards quickly learned in their encounters with Diaz. The insane toughness he exhibits will serve him well in pro-wrestling, where the kinds of brutal bumps and stunts performed on a regular basis can take a toll on the body.
Given Diaz's durability and stubborn unwillingness to concede, he will likely be more than open to taking bumps to prove himself as legitimately tough.
There is little else that Diaz prizes more than being recognized as a toughman who does not surrender. While he's unlikely to become an in-ring technician, he will be more than ready to take hard bumps that guest pro-wrestlers need to be babied through.
