The Jon Gruden-Mike Mayock Raiders quarterback tour is complete, providing plenty of fodder for speculation. The psyches and skill sets of Kyler Murray and Dwayne Haskins have been sufficiently probed.
Many with access to a microphone or laptop are convinced meetings with the Heisman Trophy winner from Oklahoma and prolific passer from Ohio State serve as evidence that starter Derek Carr is on his way out.
For what it's worth, Carr ducked the Murray issue entirely while fielding questions on YouTube, even as queries streamed his way. In truth, no one knows what Gruden will do come April 25.
