In a tweet on X, he expressed his confusion about the situation while calling out the NFLPA for not protecting the guaranteed money the team owed the DT."Knowing who Christian Wilkins is after having covered him for 5 years in Miami, I can say none of this adds up," Kelly wrote. "And if the NFLPA can't force the Raiders to honor the guaranteed money portion of his contract there isn't a reason to have that union."Omar Kelly was referring to the fact that the Raiders are voiding $35.2 million in guaranteed money that they owed Wilkins.
