No position battle at the Las Vegas Raiders' training camp will be bigger than the one at quarterback between Kirk Cousins and Fernando Mendoza. However, another dark horse candidate is working his way into the light for the Raiders at training camp: Hezekiah "Zeke" Masses. According to various reports from Day 1 of summer practice in Las Vegas, though, that simply wasn't the case. Raiders.com's Levi Edwards noted in his post-training camp takeaways that Masses actually began the team period with the first-string defense. The Las Vegas Review-Journal's Sam Gordon corroborated Edwards' report, as did Ryan McFadden of ESPN and The Athletic's Sam Warren.
