Aside from factoring in the layoff potentially affecting Jones, that was kind of a weak breakdown by Rashad. DC is the same fighter he was the last time they fought. His title win over Rumble, and defense against Gus did not showcase his improvement as a fighter. He defeated two fighters who are known to break as the fight goes deep. Jon Jones does not break, not even for pregnant women.
No one can question DC's heart, or his will to win, but he possessed those qualities the first time around, and he lost. Both fighters are in possession of those qualities. This fight will come down to who is more skilled, and DC is simply not as skilled as Jon. He's a great fighter, likely the second best LHW of this era, but Jones is the best.
