5) Menelik Watson
Menelik Watson, the Raiders' 2013 second round pick, spent most of the season sidelined with injury. He was ineffective when healthy later on, especially after falling behind with so much early time missed. The Raiders hope he can start at right tackle, and gave him most every first-team rep there during the offseason program. Without him healthy and effective, the offensive line must shift at several spots and valuable continuity built over the last few months will be lost.
