Jenkins paints Griffin as a potential coach-killer, whose ego is empowered by ownership.
Griffin is an incredibly talented player, whose coaches most likely haven't handled him properly up to this point. Not necessarily in the sense that they haven't gotten the most out of his abilities, but more so that they've physically put his career in danger.
Now, Griffin will likely play a huge role in the selection process of the next head coach of the Washington Redskins. He might not be directly involved in the process, but it's clear that whoever wants the job will have to take Griffin's skill set and overall existence into account. Griffin is the QB in Washington, and the Redskins paid dearly for the rights to his services, so it's likely that he'll be the QB there for a long time, if the ownership has anything to say about it.
On the same token, Griffin's future also hinges directly on the man who is hired as the next head coach.
If it's someone like Art Briles, who coached Griffin in college, the transition might be very easy and could facilitate the next forward step in Griffin's career. If it's someone else with less patience for Griffin's style of play, mindset and other shortcomings, it could spell the end of his tenure in Washington. Hell, he might even end up somewhere else in a couple years when his rookie deal expires.
For now, the jury is still out on Griffin. The next Redskins coach will most likely live or die with him, however, because a coach's shelf life is short, and the QB is the biggest part of his success. We'll see how it works out in Washington.
