They’ve explored both the free agent and trade market, but with little out there that made sense, they’ve decided to turn internally.
There was some that suggested Jeremy Lamb could take over the role, considering he has a game that mimics (though isn’t nearly as good) as Martin, but that’s unlikely to be the case according to the Oklahoman. Taking Martin’s sixth man role should be third year guard Reggie Jackson.
Per Darnell Mayberry:
If Westbrook isn’t himself early on, the Thunder has a terrific Plan B in Jackson. In his first postseason Jackson averaged 13.9 points, 4.9 rebounds and 3.6 assists while shooting 47.9 percent from the field. Can the third-year guard now do it for a full season? We see no reason why he can’t thanks to his size, athleticism and finishing ability. But the fact remains that Jackson has never been a focal point of the offense. He didn’t receive the primary backup point guard minutes last year until late December, and even then he often wasn’t the primary ball-handler. Now Jackson is expected to be the team’s sixth man. If he can succeed in that role Jackson can carry a second unit that is short on offensive weapons and go a long way in alleviating some pressure from the Thunder’s stars.
